Are all Solar Installations the Same?
The short answer is no, but many installers try to claim they are.
To prevent unscrupulous operators making exaggerated claims about how good their systems are, the government asks every MCS approved installer to quote using something called the Standard Assessment Procedure (SAP).
The purpose of this is to give a householder a government-approved estimate of the amount of electricity your system will produce.
Unfortunately the answer the process gives is the same for all systems of the same rated output, irrespective of the panel type or where you are located in the country.
However MCS guidelines also allow installers to use a more detailed alternative methodology, which is the approach that we use.
It offers a further sense check on estimated system performance and takes into account the following:
- Location
- Panel Type
- Precise Azimuth (Orientation from South)
- Precise Roof inclination (Angle of slope of roof)
- DC and AC cabling
- Inverter selection and suitability
- Shading
This detailed alternative methodology provides you a much clearer indication of how your system will perform and the projected return on investment.
After we have surveyed your property we will provide you with a quote which will detail both the SAP and alternative report along with a complete system design.
