2 Tesla Powerwalls installed
OUR CUSTOMERS SAY:

"Savings have been $275 to $325 per month"

Got my 32 panel with 2 Tesla Powerwalls installed a year and a half ago. I have been running 24/7 on solar power averaging 75-80%. Savings have been $275 to $325 per month. This is exactly what I was expecting when I ordered the system. Very happy with ProVision and the equipment installed. My Tesla app that monitors the Powerwalls tells me the HELCO grid has been down 10 times for 3 hrs total and I never knew it was down at all.

OUR CUSTOMERS SAY:

"The smartest investment we ever made and we have ProVision Solar and their excellent staff to thank for it."

After shopping for solar contractors Island-wide and talking with both business and household owners about their experiences, it quickly became evident to me that one firm in Hilo, Hawaii –ProVision Solar– ranked far superior to its competition. I then had them do a home visit and follow that up with a turn- key installation of the US-made system they recommended, and now 5 years later we’re living with a utilities bill that’s 1/10 of the preceding ones and have gained over $25,000 in added value to our home. This was the smartest investment we ever made and we have ProVision Solar and their excellent staff to thank for it. Particular kudos go to Kim K. for guiding me thru the process and seeing it thru to completion.
