Every building and its occupants are unique, so the more we know, the better we can recommend a power system that fits your needs and specific interests.
A view of your monthly electric usage is the fastest way to get the most accurate idea of how a solar power system will perform for your home. Utility bills are the most convenient way to gather this information.
For new construction or new homeowners when this information is not available, we can still provide a good estimate based on the size and age of the home, the major appliances, and occupancy.
While just an average month is sufficient, comparing summer to winter is more helpful. But if you would rather skip this step, that's ok too, because we can still inform you about estimated solar performance; we just won't be able to compare it to your monthly usage.
Keep in mind that sizing a solar power system doesn't have to be an exact science. Knowing your power and energy usage just helps us serve you better when you would like to know more about how solar power and battery systems can change your utility bill.
Power bill information
Please gather and provide the following details. You can provide all of the information we need using our project form.
You may call the utility and request an emailed monthly summary of usage (kWh and kW), log in to your utility account online, or use your printed copies.
Power company (name)
Type of rate (i.e. regular, all-electric, demand charge, heat meter)
Monthly energy use (kilowatt-hours kWh)
Peak (demand) power (kilowatts kW)
You may also tell us about:
Your time-of-use profile (when you use electricity most / time of occupancy)
Major appliance types: i.e. electric heat, air-conditioner, well pump, hot tub, electric vehicle, and other 240V appliances.
A copy (scan or photo) of a recent power bill (both pages) is also very helpful to show us your rates and charges. Some bills have a monthly summary on a graph, which is also a sufficient breakdown of your monthly usage. The monthly breakdown is necessary to account for seasonal change.
