We used Harrison’s Solar for our install and have regretted this decision entirely. Harrison’s did zero to ensure that the expensive system that we had payed for actually functioned properly. As an example our electrician (prior) installed two Tesla car chargers that were supposed to be supplying electricity using the solar panels and battery storage but the reality was that very little of our home usage was being supplied by our 13.6 KW + battery system which was funnelling the ‘excess’ generation at 8 cents/kwh back into the main grid and our electric bills remained high at $500 per month. When we choose not to continue using Harrison’s they sent us an invoice of $1500 as an ‘administrative fee’ to change over access to our system to another company … this costs nothing to actually do.
