How Much Would 12 Solar Panels Cost?

The inverter deserves particular attention. Solar panels produce DC electricity, while the appliances in your home use AC electricity. The inverter converts the electricity into a form your household can use.

The quote should make it clear which inverter and panels are being proposed. If two installers offer noticeably different prices, check the equipment before deciding that one is simply cheaper.

When comparing a solar panel installation Service, ask for a clear breakdown of the equipment, labour and any additional work. A low headline price may not include everything needed to finish the job.

Does The Roof Affect The Price?

Very often, yes.

A simple roof with good access is easier to work on than one with several sections, awkward access or structural concerns. Skylights, dormers and chimneys can also reduce the usable space.

Then there is shade.

Trees and nearby buildings can block sunlight at different times of the day. Energy Saving Trust notes that shading can have a major effect on generation and recommends that installers assess how shade affects the roof throughout the day and across different seasons.

A south-facing roof is generally a strong option, but it is not the only one. East- and west-facing roofs can also work, although their output will differ from a south-facing installation.

This is why a quotation should be based on your actual roof rather than a standard 12-panel package.

How Much Roof Space Do 12 Panels Need?

The exact area depends on the dimensions of the panels you choose.
