How much do solar panels cost?

The cost of solar panels has fallen dramatically over the past few decades. Customers across the world paid $125.83 (£99.25) per watt in 1975 – meaning a 3kWp system would've cost you £297,750, with all prices adjusted for inflation.

How much does a solar power optimiser cost?

As a rough guide, power optimisers cost around £40 a unit. This increases to about £180 per panel for smart solar systems. Although solar power optimisers may increase initial costs of a solar system, the increased efficiency often means a good return on investment in the long term.
