Why Service Solar Panel Systems?

Posted by Charlie McGibbon on 09 Feb 2024

Solar panels are a long term investment and it's prudent to keep the system in good working order. Like a car needs an MOT, or a boiler an annual service, a much larger investment the size of a solar array is definitely worth checking periodically to ensure everything is ticking over. There are several reasons for doing this, read on for why you should get your panels serviced and cleaned regularly.


How Often Should I Get My Solar Panels Serviced?


You might not need to invest in solar panel servicing every year, but at Spirit we recommend servicing at least every couple of years, especially for larger commercial arrays, and cleaning more frequently than that. These services come with with a price tag, depending on the size of the system, however it's not as expensive as you might expect and the loss in efficiency from not getting panels serviced far outweighs the cost of keeping the system clean and up to scratch with a regular service. Additionally, particularly for larger commercial systems, regular servicing may be a requirement requirement for any insurance policy taken out on the system and the normally generous warranties on the panels themselves may be void if not serviced regularly, so it's definitely worth checking the paperwork that came with your system for a gauge on how regularly in should be serviced. Generally, 1-2 years for servicing and annually for cleaning should be sufficient.

Solar PV for Charities to Qualify for 0% VAT

Posted by Charlie McGibbon on 26 Jan 2024

Buried by the headline announcement of 0% VAT on battery only domestic installations came a welcome bit of news for charities looking to invest in solar to reduce their energy bills, that is the announcement that charities now qualify for 0% VAT on solar panel installations where the building in question is used solely for charitable purposes. This will come into effect from the 1st February 2024.

This means that not only must the building be owned by the charity but it must be used solely for charitable purposes. There is a bit of leeway here, for example church and village halls that can be rented out but are still owned by the charity, this was already written into VAT rules that there is leeway of 5% in the term "solely", so as long as the building is used 95% for charitable purposes, the VAT waiver still applies. This expands the definition to include places like village and church halls that can occasionally be rented out, so long as the primary use is a charitable one.

The announcement also covers battery installations, so if your charity already has solar PV installed and would like to take advantage of this change to retrofit a battery, now is a very good time to get in contact.
