This is not a problem as you will own the Solar P.V. kit. The property could be promoted including a solar P.V. system that generates X kWh of electricity per year for free. This would help [...]

A kilowatt hour (kWh) is a unit of electrical energy. 1 kWh is identical to 1 unit of electricity that is shown on your electricity bill. An electrical item having a power rating of 1kW will [...]

A 250kWp solar P.V. system in the south-east of Ireland generates sufficient zero-carbon electricity to off-set approximately 100 tonnes of CO2 each year. That’s the equivalent to the average [...]

A typical rooftop installation will take 1-2 weeks to complete. Larger projects may take 2-3 weeks.

Yes. An application must be made to ESB Networks in order to connect in parallel to the grid (i.e. self-consumption on site). However, Marval manages this process from start to finish.

Currently any commercial scale rooftop solar installation in Ireland will require planning consent.Marval manages this process, including preparation of the planning documents and liaising with [...]

Once contacted by a business owner, Marval carries out an initial desktop feasibility assessment. Before visiting the site, we can establish its suitability based on a number of factors such as [...]
