Solar Photovoltaic Systems

Even with current uncertainty over long term Feed in Tariff rates after April 1st, we can be assured that up until that date, you will be able to sign up to a long term scheme on the Feed in Tariff, 43p a unit till end of March, then onto 21p a unit after that for 23 years.

There may even be a chance you'll get the 43p rate for the whole 23 years!. It depends on the ongoing Judicial Review and Governments appeal. One thing is sure though, if you don't arrange for an installation soon, available dates till March will be fully booked!

For quiet and clean electricity generation with a modular approach, Solar Photovoltaic (PV) systems are hard to beat.

The versatility of solar PV lends its technology for any electrical generation purpose you may need from small vehicle mounted battery charging systems to multi kilowatt grid connected generation installations.

Every day, during daylight, a PV system will generate electricity. It does not have to be full sunlight, but maximum output will be achieved in full sun. Cloudy days will probably produce around 10% of the rated full output. In the South West, output from a Solar PV system will be around 20% higher than from a same sized system in the north of England.

Solar PV systems, once installed, are quiet, need no maintenence and have an easily expected life of 20 - 25 years and beyond. There are PV systems built in the 1960's that are still operating right now!

The costs below represent a standard concrete pitch roof installation on a typical house. (as at January 2012) Annual FiT payments based on 21p a unit

System size	Modules	Annual power (SAP)	Installed Cost	Annual Feed In Tariff earnings*
1.5kWp 10sq mtrs	6 @ Mono 250Wp	1328 units (kWh)	£4950	£357
2.5kWp 16sq mtrs	10 @ Mono 250Wp	2214 units (kWh)	£6550	£595
3.0kWp 20sq mtrs	12 @ Mono 250Wp	2657 units (kWh)	£7200	£714
4.0kWp 26sq mtrs	16 @ Mono 250Wp	3542 units (kWh)	£9250	£951

 

 

 

 

 

 

 

 

 

*FiT earning estimates based on basic FiT payments plus an estimated 50% of power exported at 3.1p a unit. We have assumed your 'free use' electricity that will be available to power your house during daylight will consume a third of what you generate. Examples based on a South facing pitched system with minimal shading.

 

To stay up to date with modules that will give you the best annual yield, we always try to stay one step ahead, keeping an eye on industry league tables. Because of this, we have moved away from older lower yield panel designs such as Sharp to higher performance Suntech, REC, Sanyo, Kyocera and others.

 

For some while we have been specifying Suntech modules as an option with every proposal we send out. Suntech's have a great reputation for high annual generation and quality for such a super cost! They are the biggest PV manufacturer in the World! We fit these modules on our own houses to give us a brilliant return. Top of the recommend list! Yes, they are Chinese manufacture, but the biggest seller in the World, and cannot be compared to those cheap backstreet imports that are still being touted by 'bargain solar' installers. These guys know how to do it properly. See here for their website

 

REC modules really hit the spot in Europe, having again got to 1st place in Photon magazine 2011 tests. We now only install these quality panels in the black anodised frame option, as we have found most people really love the 'non-silver' and discreet look on their roof. Currently available in 240/245Wp sizes, which we keep in stock as our standard module. Also available as a 250Wp option, but currently at a slightly higher cost.

 

Sanyo HIT250 Hybrid module costs have dropped massively early this year, now making them a very attractive proposition for limited roof space, packing a 250Wp output into the same area other manufacturers can only get 185 -200Wp. Also, as Sanyo use a hybrid sandwich technology, the module will provide a slightly better yield per year than other traditional mono or poly. We now have these ex stock, along with the REC's above.

 

Click here for a data sheet on Kyocera black framed 185/190W PV modules with a higher annual yield than Sharp mono. We still keep these in stock to cater for smaller roofs as the 185's are shorter than REC, Suntech and Sanyo's.

 

We also now offer a full 10 year insurance backed warranty on all parts & labour for all our grid connected systems! This is in addition to any PV manufacturers 20 year warranty.

 

On the inside of the building we install quality electronics to match the PV array output. We try to use the trusted Sunny Boy G83/1 compliant inverters whenever possible or any emerging reliable compliant inverters such as Enecsys micro inverters, and all wiring and certification included.

No hidden extras and charges, all grid connection and electrical works and certification is included.

We now have our own scaffold tower access equipment, suitable for single storey buildings, but for 2 storey or higher there will be additional costs for scaffolding, to comply with current Health & Safety regulations.

Over the last 6 months, we have been involved with a number of new start up PV companies who needed guidance, and have been called in to repair badly installed systems by alleged PV installers who obviously did not know what they were doing. Because of this, we have started a Solar PV repair service. You can be reassurred that even if your original installer turned out to be one of the 'lash it and run' brigade, our guys are able to attend to resolve the problem.
