Host Comments

While many are in denial, the science has been very clear for decades now, with respect to Global Warming and Climate Change.  https://www.youtube.com/watch?v=2T4UF_Rmlio.  It is time to cut our carbon footprint so that one can leave behind a habitable planet for the next generation.  We don’t need to choose energy sources that leave behind polluted air and water, devastate areas where these sources are extracted from the earth, create drought, wreck our normal weather patterns and produce storms of increasing severity.  Especially when it makes no economic sense to do so.

We installed a 12.98 kW system in June 2014 and added another 3.3 kW in October 2015 to take it to 16.28 kW.  Electrical load includes 2 air conditioners (3 ton and 4 ton) a pool pump that runs 8 hours each day, a pool cleaner pump that runs 2 hours each day, electric cooktop, 2 microwaves, 2 ovens, dishwasher, clothes washer, clothes dryer, electric kettle, toaster, hair dryers, Nissan Leaf.
