Frequently Asked Questions

How Much Area is Required for a Solar System?

The area required depends on the amount of electricity to be generated. A system size of 2–5 kW requires 120-320 square feet.

How Much Does a Solar System Cost?

Typically $20,000 to $60,000 based on a variety of factors including: • The available rebates and incentives • The size of and configuration of the system • The rating and performance of the solar panels • The rating and performance of inverters and other equipment • The energy efficiency of your home or building • The method of financing the system

Is There Any Preparatory Work Needed?

Prior to installation, it is wise to increase the energy efficiency of your home or building. Install compact fluorescent lights, insulation, and upgrade to energy efficient appliances and windows. Occasionally, the roof structure will require strengthening and vents may be relocated. Bushes and trees also may be trimmed or removed.

Should I Repair My Existing Roof Before Installing a Solar System?

If your roof is old or requires repair, fix or replace it prior to the system install. This prevents the future cost of removal and reinstallation of the system.

What Maintenance is Recommended?

Wash dust and dirt off your solar panels with water and a soft brush twice per year. Tru Source can provide a maintenance schedule to wash your solar panels and check the electrical connections of the wiring and general condition of your equipment.

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 are very reliable. If any problems arise, do not attempt to repair the solar system yourself.

Will a Solar System Produce Electricity on Cloudy Days?

Yes, solar panels absorb various spectrums of visible and invisible light, however, energy production will be less than on clear and sunny days.

Does a Solar System Work in Cold Weather?

Systems work in many weather conditions and often work better in colder temperatures due to an increase in the conductivity of metals.

What is the Effect of Shade on a Solar System?

Systems should be placed where there are minimal amounts of shade from trees, other buildings, chimneys, or objects.

How Long Will the Installation Take?

Installation for a home usually takes 1-3 days depending on size and complexity.

Do Solar Panels Emit Noise?

Solar panels are silent. However, the inverter may hum slightly.

How Can I Maximize My Solar System Energy Production?

Systems are typically oriented south or west to maximize performance. Prevent shade on your solar system by keeping trees and bushes trimmed. Keep panels free from dust, dirt, and bird droppings.

Will My Solar System Produce More or Less Energy than Expected?

Weather conditions vary, which will affect the output of a system by plus or minus 12% per year.

Will Hail, Wind, or Fire Affect My Solar System?

Solar panels can withstand impacts of 1" hail, wind loads, and certain fire standards. Panels and their attachments are designed to meet local requirements and conditions.

Do I Have to be Present During Installation?

Solar systems often can be installed without the need to regularly enter the building.
