In Nebraska, the state net metering law allows customers the opportunity to sell excess energy their solar power system generates back to the customer's local electric utility. For customers who are considering installation of a solar power system and utilizing net metering, contact your local utility at least sixty day prior to installation and are responsible for all costs associated.

- How do I know if my site will work for a PV system?
Solar designers look for sites that provide an optimal southern orientation, good exposure to the sun and an adequate amount of structural support and space for solar panels to be mounted. The best location for a PV system is on a south-facing roof, but an east- or west-facing roof might also work. Flat roofs provide a base for a variety of solar modules. Locating the PV system on the ground can work with either a fixed-mount or tracking-mount (the PV panels rotate to follow the sun across the sky) system.
- How do I determine how large a solar system I will need?
The size of the system is usually directly proportional to the amount of power you use. The general rule is you should try to size your PV system equal to or less than your annual electric energy consumption.
- How much weight will a solar system put on a home's roof?
PV systems typically weigh approximately 3-4 lbs. per sq. ft., and most roofs can accommodate two to three times that amount of weight. A roof’s load capacity is generally taken into account when assessing whether a solar system is appropriate for your home, and in the ultimate design of the system.
- Does a roof-mounted PV system void my roofer's warranty and/or affect my home insurance policy?
It depends. Check with your roofer and your insurance agent. It is likely that the cost of your PV system will have an effect on your home insurance rates.
- Does cleaning the PV panels require any special expertise or equipment?
A garden hose is typically all that’s needed to clean PV panels.
