What Size System
Do I Need?
Typically 100 sq. ft of roof space will generate 1 kilowatt of electricity. An average 2,500 sq. ft. home will use 5,000 kilowatt-hours of electricity per year. This results in the need for a 3 kW (AC) system, utilizing 300 sq. ft. of roof space and will generate most of the electricity required for such a home.
Is my home or
business a good place
for a PV system?
A well designed solar system needs clear access to the sun with limited or no shading issues. You can often make a good determination yourself by identifying optimal roof lines and evaluate any shading hazards like trees, chimneys, and neighboring homes. Typically, the best orientation for solar systems is southern facing, however west or easy facing may also be acceptable.
You also want to evaluate the age of your roof. If your roof is older and needs replacement, you would want to take care of that upgrade prior to installing solar. After all, your solar system will last for 25 years and likely more!
Which Panels do you work with?
We only work with the best of breed products that we have personally tested to perform at the highest standards, to that extent we are technology agnostic and will recommend various technology platforms for different purposes. For us to install and recommend a system it must be cost-effective, available, incremental and come from a reputable company that will have a meaningful warranty.
What is the permit process like?
Each county/city will require you to apply for a permit with the building department. The requirements of each building department vary, but they tend to ask for the following documents:
- Line diagram
- Manufacturer cut-sheets
- Roof drawing / array layout
- Application
- Small Fee
Is it proven technology?
The technology has been around for over 50 years and some of the initial solar cells are still operating today. The panels are designed to produce at least 80% of their initial power even after 25 years. The efficiency and cost has significantly improved in the last 5 years. Solar has never before been so affordable or such a safe investment.
- Solar Panels come with a 25 year warranty.
- The Inverter comes with a 10 year warranty.
- Workmanship comes with a 10 year warranty.
So with this kind of guaranty, there is nothing to fear, but saving money!
Insurance
Prior to installing your solar electric system, we recommend you contact your insurance carrier to determine the impact on the yearly premium. Typically, a solar electric system will impact your premium very little, however it's best that you ensure coverage at the start of your project. Solar systems come with a long term manufacturer and workmanship warranty, however, we highly recommend your home owners or liability insurance cover the cost of unexpected issues, radical snow loads or weather related issues.
