DOMESTIC PV SOLAR PANELS

On-Grid connected PV solar panels (Photovoltaic) or micro generators very simply put generate electricity, produced from daylight through a process called photovoltaic's (PV). "Photo" refers to light and "voltaic" to electricity. Photons creating Electrons.

"PV solar panels installed in Japan in the 1960's are still going strong today"
On Grid PV Solar Panels
Generally considered the 'Mercedes' of the solar world, you can generate your own domestic electric for the next 30 years as, green issues change the world we know, while adding value and status to your property.
Photovoltaic solar panels (PV Systems) can be used for homes, offices, public buildings. As part of a grid connection PV systems can produce electricity which is sold to the National Grid, combined with basic energy saving measures.
The innovative PV array technology and mounting systems means that PV can be retrofitted on existing roofs or easily incorporated as part of the building envelope at construction stage. The benefits are:

  • Your own clean, independent renewable power source
  • Can reduce your electricity bills by up to 100% (Depending on your energy consumption rate and size of system purchased)
  • Surplus sold back to the National Grid at good rates
  • Gain valuable tradable 'Renewable obligation certificates' (ROCs)
  • Increases the value of your property
  • Low maintenance, with a long functional lifetime of 30+ years plus Silent in operation
  • It is the only renewable energy source that is proven
  • No "Nimby" or planning barriers
  • Contribute to reducing the impact of global warming and climate change.

Frequently Asked Questions

Can I use it to heat my House?
PV solar systems and solar hot water are commonly confused, which is perhaps understandable given that both can be described as 'solar power' and roof mounted panels. However, the two technologies actually bear little resemblance apart from they both harness the suns energy directly.
How much will PV generate?
A PV System would generate approximately 750 kWh/year per kWp installed. So our basic 2 kWp system would generate around 1500 kWh per year, and a 5kWp system will produce around 4500 kWh.
Will it supply all my electricity?
The average household consumption is 3000 kWh per year. Thus on average our smallest 1kW system would supply nearly 50% of your electricity over the course of the year. Though it may be possible to do more by carefully controlling your energy use.
What grants are available?
There are government grants schemes to assist with this type of solar. The DTI are offering a maximum of £3,000 per kW installed.
What does 'grid connected' mean?
The generated electricity, which will obviously vary according to the level of sunlight, will not match the pattern of electricity demand. This is resolved by connecting the PV system in parallel with the distribution network (the grid).
In this way the deficit between generation and demand can simply be purchased from your electricity supplier as normal. The reliability of your system will not be affected. Conversely, should generation exceed demand, then the surplus can be exported to the grid and sell this electricity back to your supplier.

Is my home suitable?
This is dependent on the size of your roof. The panels can be configured in many different ways to fit, but the illustration (above) shows you the sizes for each 1kW needed, or approximately 8m sq of roof space for each 1kW installed. If roof space is an issue, another option, is to ground mount them on a frame within your garden.
Do I need planning permission?
Eco Build Property can not vouch for the decisions made by your local planning authority, and we recommend that you contact them at the offset. However unless you live in a listed building or conservation area, in our experience planning is generally granted or not required for PV solar, and arrays mounted less than 10cm above the roof ridge line.
What maintenance is required?
One of the advantages of PV solar over other UK micro generation technologies, is that minimal maintenance is required because it is a solid state energy conversion process. The only requirement is for periodic cleaning of the PV arrays, for any domestic electrical installation.

PV Feasibility Equations
Your yearly electric bill x 30 years (typical solar panel life span)
+ 25% (latest energy increases)
+ 3% (yearly inflation)
= your future energy costs
This equation does not take into consideration any future energy price rises, within the next 30 years, which are inevitable. Now decide if you want to spend this money as you do now, or choose the eco-friendly choice for your children or grandchildren


Advantages of installing a PV system

  • No emissions, No Noise
  • No maintenance (no moving parts to wear out)
  • Integrated into or mounts onto an existing building
  • Visually attractive
  • Questions when choosing a PV Solar Panels system
  1. How much roof space do I need?
    The system does take a lot of roof space, but (photovoltaic) pv systems can be installed within your garden area using 'A' frames, facing south, if roof space is a problem.
  2. Are they manufactured within the UK, supporting British manufacturers, helping us become a leading renewable energy supplier to the up and coming worldwide industry?
    Yes please support British industry.
  3. I heard PV systems are expensive.
    With generous DTI grants available, and the increase in your house price after install, with relief from the up and coming energy prices, investment in such a system, has now become a real option millions of homes across the UK.
  4. Can I sell my surplus energy?
    Yes, ROC's (Renewable energy certificates) are credited to you and tradeable. As energy prices rise, these are increasing in value, earn everyday, and the more you save energy within your household, the more you will earn.
  5. Will installation have a large impact on my home?
    Once the solar panels are installed on the roof with scaffolding, the inside components do not take any inside space up. Installations usually can be done within 3-4 days, with installers being considerate, clean and tidy.
  6. What size solar panel system will I need?
    This depends on your energy consumption rate. You can find this out by looking at your electricity bill. (Kwh). We can help you work out what size pv system is required for your household.
  7. Do I need planning permission?
    Only if you live within a conservation area, or in a listed building. It is worth contacting your local council beforehand.
