If your solar system is still covered by warranty from the company that installed your system, then the installation should be covered, they should pick up all the costs.
Often the panels have 20 – 25 year warranty, and the inverter 5 years, but anything else may only be a one year warranty.
If you are still covered by warranty, call the company you bought from first as they should come and fix it.
If you no longer have an installation warranty, and your system is in need of repair or maintenance please call us.
Most solar systems (especially large ones) are a considerable cash outlay and if they aren’t performing as they should you aren’t getting value for your money.
If you are unsure a five minute phone call could save you money and heartache.
