Wivey solar installations and output

Solar electricity installations in Wiveliscombe and their output

Known solar electricity installations in Wiveliscombe are listed in the table below (last updated November 2016). There are 12,084 panels at the Sandys Moor solar farm on the edge of town and in addition 1,395 photovoltaic (PV) panels on 70 roofs of domestic, commercial and education buildings and two more ground-mounted installations (one domestic, one business). This is a total of 13,479 panels, which is an average of over 10 panels for each household in the town area.

Wivey’s 13,479 solar panels have an average annual output of about 3,268 MWh or 3.27 million units, which is 59% of Wivey’s annual domestic electricity consumption*** and saves the equivalent of about 1,750 tonnes of carbon dioxide emissions every year.

Performance data supplied for south-facing Wivey installations shows these are producing an average of 1,004 kWh per annum for each kWp of installed capacity (kWh/kWp). This is a little above the standard annual value of 972 kWh/kWp for an optimal roof in our zone, which is published in tables used for installer estimates. However, some local installations are performing  even better than this and some not so well, which will be due to other site or technology factors.

More on these statistics and my estimate of Wivey’s solar output is given in these blog posts, including in further comments of replies.

Click on links below for further details and photos for some of the systems, including more performance data and installation photos. Please email me with further and missing information, including for any other local installations. It is helpful to confirm panel or system power ratings and to receive data for solar generation (in units or kWh) over full years, but any 12 month or more period is fine with start and end dates for the readings.

* kilowatt peak power rating
** Annual generation – kilowatt hours per annum
*** Calculation based on official energy statistics, which shown average (mean) domestic electricity consumption in 2014 in Taunton Deane was 4,228 kWh. Total households for Wiveliscombe (Town Council area) is about 1,310, so total domestic electricity use should be about 5,540 MWh.
e = estimated generation and output based on number of panels, their orientation and power rating if known
A = based on actual readings supplied for one or more years

More about the calculation for estimating Wivey’s solar output is given in these blog posts.

Online solar advertising targets Wivey

I have received enquiries about recent online advertising, which is targetting people in Wivey and saying that solar funding is available “with ZERO up from costs”, which has “just opened up in Wiveliscombe from June 26th”.

Solar Enquiry

There are plenty of reasons to doubt this offer. Why has it just opened up in Wivey? Why are no contact details given? It sounds too good to be true? What are they not telling you?

I contacted them to find out more about what is really offered. The representative I spoke to on phone was OK and not too pushy. He was keen to arrange for someone to come to see me when full details could be provided, but he accepted that I would think about it and contact them. He rightly highlighted the savings on electricity bills and quoted the correct rates for support currently available to all through the government’s feed-in and export tariffs. He didn’t mention homes needed to have an EPC energy efficient rating of level D or above.

The company behind the offer is Project Solar, which is not stated on their website advert. They are based in Manchester and have not opened up a new local office.

They offer loans over 5, 10 or 15 years at an interest rate of 9.9% per annum, although also said buying outright was best. The rep said they had to visit to give accurate costs, but indicated it would cost £6,000-9,000 and that 14 panels would be about £6,500, which I assume would be for a typical domestic system with a peak power output of 3.5-4 kW.

This system cost is OK but it is likely that you would get a better price by inviting quotes from local installers. Their interest rate for a current loan is very high – the best rate from Nationwide is currently 3.4% and you may do even better by adding the cost to your mortgage.

What not like

I expect there would be a harder sell from a rep making a home visit. In the small print on their website (above), they indicate electricity bills increase by 7.28% and inflation by 3.04% per year. Such large annual increases would result in savings in the future looking very high. Their electricity bill increase looks particularly high and you should be able to do a lot better than this, including by switching suppliers.

Google reviews (22) for Project Solar indicate they have had some satisfied customers while others much less so, complaining of high pressure sales techniques.

I advise against going with this company. You are likely to get a better deal though a recommended local installer. And if you want to avoid up front costs, take out a loan yourself to pay for the cost. If earning a good return is important, check the estimates provided in quotes by installers carefully and note how long it will take before the system will pay for itself and before you will move into profit. It may be about 10 years, so be confident that you are likely to stay in the house for that long, as you cannot take the feed-in tariff with you (it transfers as a benefit to the new owner but you will still have to pay back any loans taken out).
