Use Free Sunlight to Produce Electricity

Wessex ECOEnergy installs high-quality, high-performing Solar panels manufactured in Germany, the UK, the USA, China and South Korea. We also specialise in fitting the most atheistically pleasing systems using where possible In-Roof systems that add value to your home or business and make the solar panels less obvious.

Depending on your property and the number of occupants we can recommend a solution to fit the energy you consume. Wessex ECOEnergy will assess your needs and help you decide with a clear proposal including all financials.

Financial Benefits of Solar PV

The overall financial benefit of a Solar PV system is the sum of two elements:

Using the energy you have generated

If you can use the energy you have generated from your Solar array, (instead of paying for it from the National Grid), then you have the ability to reduce your yearly bill significantly. Wessex ECOEnergy can guide you through how to maximise this and the additional products that can help you like Solar batteries, immersion controllers and visual aids that show your available energy for use.

Selling the electricity to the National Grid

It is estimated that most households export approx. 50% of their energy back to the grid and businesses about 25%. From January 2020 you could sign up with a SEG (smart export guarantee) approved energy company and benefit from selling any un-used energy back to the grid.

System Diagram

A Solar PV system is very easy to retro-fit into any home or business with minimum disruption. Ideally, the roof will be South facing for the optimum capture of sunlight. Contact us today for an assessment to see what returns you are likely to receive over 20 years.

System Configuration & Costs

All systems are tailored to our clients situation. Factors that effect this are:

Annual energy usage in kWh
Available Roof size and orientation

With this information from the site visit, Wessex ECOEnergy will calculate your overall energy demand and create a detailed proposal showing the recommended number of panels.

Frequently Asked Questions

How accurate are your figures for performance and expected financial benefits?

The performance of Solar PV systems is impossible to predict with certainty due to the variability in the amount of solar radiation (sunlight) from location to location and from year to year. This estimate provided is based upon the Government’s standard assessment procedure for energy rating of buildings (SAP) and is given as guidance only. It should not be considered as a guarantee of performance.

Where can I place my Solar PV Panels?

Solar PV arrays can be mounted in a range of locations but the roof of a building usually provides the best and simplest site. Flat roofs are not ideal as it is hard to make them water tight once the bolts to secure the panels are drilled in. However, ground solutions are available if your roof is unsuitable using ballasts or specially designed mounting frames.

Do I need a South facing roof?

For the best performance a South facing un-shaded roof is ideal and will generate the best returns. Other orientations will work but contact us to discuss in detail.

How much electricity do Solar PV systems generate?

An optimally orientated, un-shaded 1kWp array will, each year, generate approx 850kWh (units) of electricity.

How do Solar PV Cells work?

Photovoltaic (PV) cells convert radiation from the sun into electricity. A typical PV cell consists of a wafer of semi-conducting material, usually silicon, manufactured with two electrically different layers. When sunlight hits the cell it excites the electrons within the silicon, creating an electric field across the layers and causing a flow of electricity.

What warranties are available?

Every Solar PV product that Wessex ECOEnergy supplies have performance warranties ranging between 20-25 years. The inverters come with up to 12 years manufacturers’ warranties.

What size do Solar PV Panels come in?

PV systems are modular, allowing a great degree of flexibility in design and specification. In practice, the size of a system is often determined by the available roof space or the energy requirement of the property. A standard 1kWp PV array will occupy at least 8m² of roof.

What is the difference between Monocrystalline cells and Polycrystalline cells?

There are several types of PV cell. Monocrystalline cells are made from a single large crystal of silicon – they seen as more efficient and slightly better in low light conditions but they can be more expensive. Polycrystalline cells are made from cast blocks of silicon that contain many small crystals and are slightly less efficient than Monocrystalline cells. In practice, for a typical residential property, there is little difference in the performance of these different products.

Can I sell the electricity I generate from my Solar PV system?

Yes you can from January 2020 via the smart export guarantee (SEG).

You ask in your survey “What material is your roof made from?” – What difference does it make?

The cost of the installation may be increased for slate or clay tiled roofs, as the PV systems are secured to the roof using stainless steel “roof hooks”. These hooks provide a very robust means of attachment and don’t compromise the weather proofing of the existing roof. Fixing these hooks to concrete tiled roofs is a relatively straightforward process. However, due to the way slate and clay tiles are laid, many more need to be removed to fit the hook, and layers of flashing are needed for weatherproofing – hence these installations are slower and more costly in terms of labour.
