Solar installers
in Cornwall

10+ years installing Solar PV and Heat Pumps in Cornwall

At Harvest Cornwall we have extensive knowledge and experience on a wide variety of installations.

Our expertise

Harvest has an extensive experience in multiple installations: 

  • Slate/concrete tile/flat/corrugated roofs
  • Integrated roof systems
  • Ground-mounted systems
  • Domestic/Agricultural/ Commercial/Schools
  • Battery storage solutions
  • EV charging
  • Electrical immersion connection to support hot water cylinder 

Due to the varying nature of roof types, coverings and available space, we offer many solutions, using a diverse range of manufacturers. We do not supply one brand. We provide the best solution for each individual property.

What is solar PV?

Solar panels provide you with free energy. Solar PV arrays conduct electricity from the sun using framed silicone cells exposed to light. Solar panels convert sunlight into useable electricity, capable of powering your home. We’re able to install domestic and commercial solar that generates energy even on cloudy days. Solar PV does not need direct sunlight. It can generate energy not only during sunlight hours but also in times of low light. 

Solar Panels Survey

In Cornwall, we are fortunate enough to have more usable daylight hours than any other part of the country. These are the important factors we consider at a solar panels survey:

Roof pitch

Our experienced surveyors always conduct internal roof surveys, but when a pitch is below 30°, extra calculations are needed. If data shows insufficient weight load capabilities, then strengthening is needed to and we offer this within the installation.

Roof orientation

This is possibly the most important factor when considering where to put your solar PV. The optimal orientation on the compass point is 90° East through to 270° West. Anything outside of this, facing North, is not subject to the same solar gains. 

Array design

Once accurate measurements have been taken we then draw it out to on 3D software to scale.  This enables us to try various layout options for the solar panels and we can look at the best size panels to maximise the available space. 

Panel output

Due to export limitations placed on homeowners by the district network operator, there is a restricted available output for domestic properties. However, we are able to install arrays with far higher outputs. This is achieved by restricting how much is exported. 


A detailed shading analysis is carried out using industry leading software. It takes into account both near and far objects. Our software creates a year round sun path which can even include leaf coverage from nearby trees.

Mounting System

At Harvest Cornwall, we specify roof mounting kits that consider high wind loads. We air on the side of caution by specifying the most robust roof hooks and rail available. The mounting kit can never be over-engineered and the difference in costs for upgrading is very little. 

Solar Installation

Our team of solar panel installers can expertly fit your solar array within a day. All panels will be tested and checked by our solar panel installers to ensure they’re performing to their maximum potential.

Solar Smart Monitoring

Our SolarEdge monitoring systems assess the performance of your whole array but also monitor the performance of each individual panel. 


Commercial Solar

Commercial solar panels are a great way of protecting your business against rising energy costs, whilst illustrating green credentials.

Solar Panel Paybacks

The solar panel paybacks are what make installing an array worth it. As solar panel paybacks continue to rise, solar is becoming more affordable than ever.
