Frequently Asked Questions

In a nutshell, if you install an electricity-generating technology from a renewable or low-carbon source such as solar PV or wind turbine, it is likely that you can get paid for any electricity that you export back to the grid. These tariffs are currently used in many countries, including Germany, France, Spain, Australia and some part of United States with great success.

A PV system would generate approximately 750 kWh/year per kW installed so a 4kW system will produce around 3200 kWh (this estimation is based on South orientation and no shading)

Installing PV solar is a great way of 'future proofing' your home.

The cost of a solar electric system depends on several factors but is usually based on system sizes. Contact Solid Renewables for our PV price list.

The average household consumption is 3000 kWh per year. Thus on average, our smallest 1kW system could supply nearly 25% of your electricity over the course of the year, depending on your consumption rates and it may be possible to do more, by carefully reducing your energy use.

Unfortunately the indicators are that prices will rise.

As a recent Financial Times article points out, the cost of energy, resources, materials and manufacturing is rising globally. It's likely that solar panels will never be cheaper than they are now as future panels and installations will consist of inputs (energy + materials) that cost far more than today.

The generated electricity, which will obviously vary according to the level of sunlight, means the excess energy produced will be directed out to the National Grid, and you will be credited accordingly.

In this way the deficit between generation and demand can simply be purchased from your electricity supplier as normal.

Photovoltaic (PV) panels can be configured in many different ways to fit. The innovative PV array technology and mounting systems means that PV can be retro fitted on existing roofs or easily incorporated into new builds.

No planning permission is needed, unless you live in a listed building or conservation area.

Photovoltaic systems have low maintenance requirements. However, periodic maintenance routines carried out by the system operator or the installation firm help to avoid faults and long downtimes, which, in turn, optimizes the yield. In order to carry out servicing and maintenance, it is necessary to have the operating instructions (especially for the inverter) and good system documentation that should contain recommended maintenance items. The inverter's fault display should be checked on a daily basis, if at all possible. In parallel, the operating results should be read off, noted down and checked once a month. Systems for automatic fault and operating data monitoring with a notification function make the system operator's task easier in this respect.

The system does take a lot of roof space, but pv solar can be installed within your garden area using 'A' frames, facing south, if roof space becomes an issue.
