"Wonderful, it was a very quick and easy process. Brian talked us through it and in no time we had a 3KW system mounted on a frame in the garden and the invertor installed in the basement. Brian talked us through working with our power company to get the system checked and approved and we now get credits from the power company for power we provide to the grid. In addition we are set up to get Solar Renewable Energy Credits (SRECs) payments for providing clean energy. We also got a free Energy Audit which helped locate some problems areas we were able to fix. The system has basically cut our energy costs in half. I have hesitation in recommending them to anyone interested in solar energy."

"Gave the quality rating based on what I've been told and seen but they haven't done my work yet. Also doing windows & facia and soffit work plus roof vents. As we've been looking at some things we had considered, we've reviewed some of our options. Their willingness to help us do and get the best job possible done, allowed us to expand our agreement. We are now going to do another project and are working on referring Rick to some of our contacts who have work."

Energy Efficiency Auditing FAQs, answered by experts

Upgrade to double-glazed glass or apply energy-efficient coatings to reduce heat loss and utility costs.

Motion-sensor lights use one watt while on standby and five watts while turned on. They’re usually on for one hour over a 24-hour period, bringing the total wattage to about 28 watts per day. LED lights use around 6.5 to 8 watts while on. If you leave an LED light on all night, with night ranging from 10 to 14 hours, you’re looking at using 65 to 112 watts a night. You can minimally cut your wattage in half by switching to a motion-sensor light.

R-value is calculated by dividing the thickness of an insulation material by its thermal conductivity. The material's composition and density influence thermal conductivity. Materials with lower conductivity values provide better insulation. The higher the R-value, the better the material is at insulating, helping homeowners select insulation that meets the energy needs of their climate and home layout.
