Install A Home Solar Power System

Installing a home solar power or wind power alternate energy solution saves money and saves our environment. This article summarizes the typical solar power components.

As we all know, the world is currently facing a significant energy crisis. As such, it only makes sense to make the slight up-front investment in an alternate power solution at home. Not only does it help the local energy crisis struggle, but also helps save power for the entire world. Installing a home solar power or wind power alternate energy solution saves money as well sav es our environment.

Among the alternate power solutions, the home solar power system and the wind power system are the most popular and are becoming more cost-effective and far less cumbersome than in the past. Wind power is one great solution, just not all of us can deploy it at our homes because of minor requirements. To implement a wind power system, we need a fairly large area and have an average wind speed of the area at least 11 miles per hour. Although these requirements are very easy to meet for most, in comparison, the solar power system is typically easier to implement. The only requirement is an abundance of sunlight.

A complete solar power system can have many different elements. Typically, people implement a few or all of these components, as needed. A few of the most common components are as follows :

Solar Cooker: A solar cooker is one of the most popular solar energy system that is typically used in homes. It has several advantages :

No use of fuel : solar cookers do not use any fuel other than sunlight, which keeps you saving power and decreasing those electric bills.

No polluted emissions : solar cookers do not emit any gases to the atmosphere nor does it produce residue. It makes for the most eco-friendly cooking system.

Variety of cooking : You can roast, boil, and bake, etc!

Healthy cooking : The food prepared by means of a solar cooker is very healthy. You can typically prepare meals for family of about 5 in a small cooking box all at the same time.

Solar thermal system : Installing a solar heating system or solar thermal in your home can provide your home’s temperature requirements. It allows you to maintain a steady temperature in your home without the worry of electric bills. Due to its increasing popularity, heating systems have become not only cost-effective but also aesthetically pleasing.

Solar generator : A solar generator is simply a device that can run all your electrical appliances and more utilizing our earth’s free solar energy. This device can convert solar energy into electrical energy by means of solar cells called photovoltaic cells, storing energy in these cells for later usage. A solar generator is sometimes also referred to as the solar lighting system. Simply put, installing a home solar generator is such a wonderful power-saving and cost-effective idea. Just think of getting all that free electricity!

How does solar power really work and how can you benefit from it in your home? In the following I will try to answer these and other questions, so keep on reading…

Solar energy is basically energy gathered up from the sun. This energy is extremely powerful, it is available on every part of the world and is it just waiting for us to take advantage of it. Solar energy is unlike most other energy sources completely inexhaustible. It is only a small fraction of the sun’s rays that hits Earth, but is more than enough to provide the entire population with all our power and energy needs.

The biggest issue is to learn how to gather this energy efficiently and in a manageable way. Today many different methods exists to take advantage of this gigantic power source and these technologies are constant being refined and developed. The concerns about the availability of the conventional energy sources and the fluctuating prices are causing many people to take interest in utilizing renewable energy sources, like solar energy.

It is reasonable to expect a further improvement of the solar power technology the exists today and the invention of brand new way to use solar energy over the next decades.

For the time being the most well know and tested methods includes:

Solar cells: Solar cells are also know as photoelectric or photovoltaic cells, and as the name implies these cells turn sunlight into electricity. Solar panels consists of modules of combines solar cells.

Solar water heaters: Water is heated from the heat from the sun, through glass panels installed on roofs or other places with access to the sun light. These glass panes are known as solar collectors and they utilize the heat from the sun (called solar thermal energy) contrary to solar cells which uses the sun’s light.

Solar furnaces: A relatively new solar power method, which uses reflective surfaces like mirrors, to concentrate the rays from the sun into a single point. In this single point an extreme amount of energy is concentrated, which can be used to create electricity or used in the electrolyses process of creating hydrogen from water.

The benefits of solar energy:

• Inexhaustible energy source.
• Free to use.
• Completely pollution and waste free.
• Can be used in remote and almost uninhabited parts of the world.
• High scalability, can be used for low power purposes as well as high power.
• There is no need to process the energy source before use (unlike fossil fuels).

If you’re thinking about getting home solar, you’ll most likely get solar panels for homes placed on the roof of your home.  Here’s why.

• Your roof receives the most direct sunlight for the longest period of time than any other part of your property.
• The panels are unobtrusive sitting on your roof.  You won’t be able to see them, and where possible they will be placed on the back slope of your roof.
• They don’t take up any space you want to use for other things.  If you’ve got lots of open property, this may not be an issue for you.

Here are some things to consider when evaluating your roof for solar:

Age of your roof

Examine your roof to check for weather damage or wear and tear. If it’s been more than 20 years since your roof has been tended to, a specialist should look at your roof. Since solar panels for homes have long lifespans, the wise decision would be to do any roof updates that will need to be done before the installation. That way, once your solar system is up and running on top of your home you won’t have to think about anything and just let your system create your family’s electricity.

Available space

solar panels for homes take about one square foot of space for every 10 watts the system will produce. Therefore, if  you want 3000 watts produced on your home, you will need about 300 square feet of open space on your roof for panels. This means planning your system’s design around any fireplace chimneys that would block the panels. However, even if you install a smaller system that doesn’t cover all of your energy needs, the solar system will still offset some of your utility charges…allowing you to make the most of a small roof space and still creating some renewable energy.

Direction of your Roof

The most effective solar panels for homes are on roofs that face south in the Northern Hemisphere, that way the solar panels for homes get maximum exposure to sunlight. Houses that face east or west can still generate solar power and an installer will alert you if your house fits in this category.

Type of Roof

Installers have been doing solar for many years and are well educated in the different types of roof that are supportive of solar. The easiest type of roof for installers to work on are composite shingle roofs and the most difficult ones are wood-shake roofs. Massachusetts’ popular roofing option of slate roofs are not compatible with solar installations.  In general, most roofs can hold solar panels for homes but there may be added fees for more equipment and steep angled roofs.

Angle of Roof

The angle of your roof can make a difference in your solar system’s price. For example, the steeper your roof is the harder it is for installers to navigate and install the panels. Installers may add on extra charges if your roof is incredibly steep and hard to work on, but you will still get solar panels for homes. Flat roofs require more equipment because of the reverse tilt that goes on under the brackets to tilt the panels to make sure as much sun hits them as possible.

Shading

Making sure there are no objects blocking the sun from hitting the solar panels for homes is very important. If surrounding trees are proving to create shade, you do have some options.

As the foundation of solar panels for homes, investigating and investing in your roof beforehand is always a good idea. Once you do so the next step is taking the plunge into solar panels for homes and reducing your dependency on dirty forms of energy!

<img class=”alignleft size-medium wp-image-5792″ style=”margin-right: 11px; margin-top: 6px;” title=”home solar panels for homes” src=”http://blog.sunrunhome.com/wp-content/uploads/2010/01/iStock_000007078510Small-300×200.jpg” alt=”home solar panels for homes” width=”395″ height=”262″ />Technological terms, by nature, can be a mouthful.  But their acronyms can be just as esoteric.  PBI, kWh, SREC?  Enough is enough.  Today we’re going to unpack these solar abbreviations and show home solar for what it really is: simple and relevant.

Let’s start with the basics:

• PV (photovoltaic): is a cell that converts solar radiation into direct current (DC) electricity.
• Si (silicon): a semiconducting material found in most solar cells.  It absorbs photons in sunlight and creates energy.
• kWh (kilowatt hour): a unit commonly used to measure energy delivered to customers by electric utilities.  It can be understood as the amount of energy consumed by a 1000-Watt appliance running for 1 hour.  For example, the average American household uses 920 KWh/month.  This is equivalent to running your microwave for 920 hours in a single month.
• MWh (Megawatt-hour): 1 MWh is 1000 kWh.  This unit is often used to measure larger amounts of electrical energy in power generation and that consumed by industrial customers.
• DG (distributed generation): also known as on-site generation, DG is when electricity is generated close to where it is used, such as your roof.  Generally, DG reduces the amount of energy lost, size and number of power lines and power plants necessary to transmit energy from generating stations.
• NEG & NEM (net energy generation & net energy metering): with home solar, you can end up generating more or less electricity than you use.  NEG is the total electricity your panels produce minus the electricity you use from the grid.  NEM means that the electricity you do generate will feed into the grid and earn you credits against the electricity you do pull from the grid.  Your utility bill will then reflect only the net energy you’ve pulled from the utility.

The next step is paying for solar.  Following is a list of abbreviations that address solar financing and government incentives.

• PPA (power purchase agreement): a financing option for residential solar in which a solar company owns (and installs, monitors, maintains) your solar panels for homes; you pay for electricity.  With PPAs, you avoid the high upfront costs of installing solar and pay a monthly rate that depends on how much energy your panels produce.
• UFI (up-front incentive): a payment or rebate up front for installing solar panels for homes.
• PBI (performance based incentive): a payment or rebate paid based on actual energy production, compared to a UFI, on a $/kWh basis.  A PBI benefits those with larger solar power systems.
• ITC (investment tax credit): the federal ITC is a 30% tax credit for installing a solar system in your home.  You can apply this credit to your tax bill in the following spring.
• PTC (production tax credit): the federal PTC is a per-kilowatt-hour tax credit for generating electricity, for a certain period of the solar system’s operation.  Those who are less interested in PTCs can apply for an ITC, and vice versa.
• EPBB (expected performance-based buy-down): an EPBB is a type of up-front incentive based on an estimate of your solar system’s expected performance.  The performance estimate is based on system size, geographic location, orientation at time of application.  The EPBB incentive is offered only to systems smaller than 30 kW AC in California, under the California Solar Initiative.
• PACE (property assessed clean energy): cities are beginning to offer PACE programs which provides a loan for your solar panels for homes.  The program pays for the panels and you pay for the solar system on your property tax bill, over approximately 20 years, with interest.  PACE provides loans for the cost of the panels, before the federal ITC is rewarded – this means that you will need to make payments on a larger, pre-ITC loan.
• SBC (societal benefits charge): funding for programs that provide benefits to society, such as low-income, energy efficiency, and renewable energy programs

Some states not only offer financial incentives but also encourage solar energy production through other means.

• RPS (renewable portfolio standard): an RPS provides states with a way to increase the generation of renewable energy using a market-based approach.  It requires utilities and energy providers to supply a certain percentage of their electricity from renewable sources.  Right now, states with RPS requirements require between 4 and 30 percent of electricity to be generated by a specified date.
• SREC (solar renewable energy certificate): an SREC is the property right to the environmental benefits associated with generating solar electricity.  Homeowners who generate solar electricity are credited with 1 SREC for every MWh of electricity they produce.  Utilities that have to fulfill an RPS requirement can purchase these SRECs on the open market.
• ACP (alternative compliance payment): Utilities that have to comply with RPS requirements but find SRECs to be scarce or unavailable can provide an alternative payment (i.e. $300/MWh)

Whether you want to learn more about solar or help bring solar to your state, you’re not alone!

• ASES (american solar energy society): the nation’s leading non-profit association of solar professionals and advocates.  ASES publishes a solar magazine, organizes conferences, and has over 13,000 national members.
• SEIA (solar energy industry association): the national trade association of the solar industry.  SEIA works to make solar mainstream by advocating for federal policy that removes barriers and improves market conditions for the U.S. solar market.
• CSI (california solar initiative): the second largest solar initiative in the world, after Germany, and the largest program of its kind in the United States.  The CSI is part of the Go Solar California campaign and aims to ensure that California generates solar and reward systems that provide maximum solar generation.  This initiative builds on years of state rebates and offers incentives based on performance factors, in order to lower the cost of solar systems for consumers and build a self-sustaining solar market.

We hope that this helps make residential solar easier to understand.  Though it can seem complicated — especially if you’re dealing with installation and financing on your own — home solar is one of the simplest ways you can save energy, cut costs, and help the environment.

SunRun’s first home solar system was installed this week by REC Solar in Boulder, Colorado.    Homeowners Humberto and Kendra took advantage of SunRun’s Colorado offer:  $0 to upgrade their home to solar.   They’ll start saving immediately with clean solar energy.

Have you been thinking of going solar? Well, one important thing to look into is if the trees around your house shade your roof. Even if your roof is shaded partially, this can be a solar deal breaker.

Shade and solar are directly linked. How so? The amount of shade that hits a roof correlates to the productivity of a roof’s solar panels for homes. If even only part of your roof is covered in shade, it will still dramatically reduce the system’s charging power. If one quarter of a roof is covered, the shade will reduce the output of your system by 50% and sometimes unravel the entire system.

Why does this happen? Each panel is composed of many different cells that are all connected and rely on each other to perform for overall production. The panels are equipped with sensors that reroute the electrical currents maneuvering around the cells that are not performing. In an effort to correct the production output, this rerouting serves to lose the potential energy created and lowers the voltage in the string of cells (Shade Happens). As a result, the shade that feels so nice in the summer months actually hinders your home’s solar potential.

That being said, before committing to solar, check that your house has a roof plane that does not face north with unobstructed sunlight.   See if any nearby trees block direct sunlight from hitting your roof at various time of day.

If you are interested in going solar but you have a lot of trees or your neighbor’s trees cast a shadow on your home, you have several options.

1. If you are willing to part with some trees on your property, trim them back or cut them down. Be certain to check watershed and other environmental factors if your are engaging in a significant tree-removal project.  In exchange, plant other greenery such as hedges or gardens on your property and power your house via solar energy so you can get the best of both worlds.
2. Negotiate with your neighbors explaining your interest in going solar and how their trees would prevent a solar system from working. Offer to help pay for the removal of trees and the replanting of other bushes or smaller trees that won’t shade your roof and prevent your solar system from running properly.

If solar is something you are very invested in, make sure that there are no barriers that would prevent your system from running effectively! Remember, there are ways to go green and still maintain the greenery in your yard.
