How much do solar panels cost ?

The cost of installing a 4kWp solar PV system has more than halved since the early days in 2011 to between £6,000 – £7,500 depending on the specification of the system and the method of installation.

Even if you factor in the cost of having a replacement inverter installed during the 25 year lifespan, the savings made exceed the system plus replacement costs.
