How do I find a solar provider?

Most solar providers are found in your local phone book under Solar, or check with your state energy office for a list of companies. Some internet sources such as www.findsolar.org are also helpful.

What should I look for in a solar provider?

Look for experience, proper licenses, insurance, references, close proximity, and a provider you feel comfortable with. To get a reasonable price, solicit bids from several providers and compare their offers:
• Do they provide you with a timeline and checklist so you know what to expect and when?
• Do they offer on-site inspection, bill analysis, and provide a multi-year financial and energy prediction?
• Will they handle all paperwork, permits, utility agreements, etc.?
• Is there a full system warranty for five-years (or more)?
• Have they properly accounted for all shade, such as future tree growth or new nearby buildings?
• Do they include maintenance checks or cleaning of the solar system?
• Is there a monitoring package included, so you can view the results at your house or via internet?

Is there any preparatory work needed within my house?

Yes, before you install a solar system, it is best to increase the energy efficiency of your house. Install new compact fluorescent lights, insulation, and upgrade to energy efficient appliances and windows. When your house is more energy efficient, the solar system you purchase can be smaller (and cost less!) to meet your houses’ energy needs.

What maintenance is recommended?

Wash dust and dirt off your solar panels twice per year with water and a soft brush. An easy solution is to ask a local window washer to clean the panels. Also, have a professional check the electrical connections of the wiring and general condition of your equipment once per year.

How can I maximize the power my solar system will produce?

Solar systems should be oriented south or west to maximize performance. To prevent shade on your solar system, keep trees and bushes trimmed and wash panels as needed to keep off dust, dirt, and bird droppings. Allow space between your roof and panels to let air flow underneath and keep panels cool.

How much does a solar system cost?

Typical prices are $20,000 to $60,000 based on a variety of factors including:
1) Your circumstances, such as whether or not you finance your solar system
2) If rebates or other incentives are available in your area
3) The size of your system
4) The energy efficiency of your home
5) Whether it is a new or existing building
6) Whether the solar system is integrated into the roof or placed on top of the existing roof
7) The rating and performance of the solar panels
Other equipment such as inverters and optional monitoring packages
9) System configuration and
10) The solar provider you choose

Why did my solar system produce more (or less) energy than expected?

Weather conditions vary from year to year so your system may produce more or less than is estimated. Weather values can affect the output of a system by plus or minus 12% per year  Source: DOE).

How long will installation take?

The ease of installation makes solar systems an easy choice for most consumers. Installation
for a house usually takes 1-7 days depending on the size and complexity of your system.

Do I have to be at the house when it is installed?

Talk with your solar provider about time requirements. Often, solar systems can be
installed without the need to regularly enter the house.

Do I need to add anything else, like lightening rods, roof structures, etc.?

Your solar provider will know the details of connecting your system to the electric grid and complying with local codes. They will advise you about any additional components that may be necessary.

What happens if my solar system breaks or stops working?

There are no moving parts to break (meaning no mechanical wear and tear) so systems
will last many years without failure, but if it does stop, contact your solar provider and
request a visit. To be safe, do not attempt to repair the solar system yourself.

Do solar panels emit noise?

No. Solar panels are silent. However, the inverter may hum slightly.

Will a solar system produce electricity when it is cloudy?

Yes, because solar panels absorb various spectrums of visible and invisible light, but the energy produced by your solar system will be less than when the sky is clear and sunny.

Does a solar system work in cold weather?

Yes. Solar systems work in many weather conditions, and often work better in cold temperatures during winter months because cold temperatures cause an increase in the conductivity of metals.

Does shade affect my solar system?

Yes, your solar system should be placed where there are minimal amounts of shade from trees, buildings, chimneys, or objects.

How much space do I need for a solar system?

The amount of space your solar system needs depends on the amount of electricity you want to generate. Most homes require between 120ft2 – 320ft2, equivalent to a solar system size of 2 – 5kW using SANYO HIT panels.

Should I repair my existing roof before installing a solar system?

Yes, if your roof is old or requires repair, fix or replace it at the same time you install a solar system to avoid future costs of removal and reinstallation of your solar system in order to access your roof.

Will hail, wind, or fire affect my solar system?

Solar panels are tested to meet certain safety requirements such as impacts of 1″ hail, wind loads up to 50PSF, and certain fire standards. Your solar provider will attach and install your system and ensure it meets local requirements.

How can I help get more solar in my community?

1. Vote for pro-solar politicians and elect Earth-friendly leaders.
2. Encourage local leaders to offer solar financial incentives to your community.
3. Donate time or money to a nonprofit solar organization.
