Frequently Asked Questions

Solar PhotoVoltaics (PV) is the technology which converts light into electricity. Using semiconducting materials, a photovoltaic system employs solar modules, each comprising a number of solar cells, which generate electrical power. SolarShare PV installations may be ground, rooftop, wall mounted or floating.

Solar Power has specific advantages as an energy source: Once installed, its operation generates no pollution and no greenhouse gas emissions. It is scalable in respect of variance in power needs.

When solar power is created, it must be used immediately, otherwise your unused electricity will spill over to the Irish grid. To avoid spilling your excess electricity to the grid, a battery is needed. A battery stores electricity generated for use at another time and also stores any excess unused solar energy. Another option for storing excess electricity is to divert it to your immersion. An ideal scenario is to store any excess in both your battery and your immersion.

The battery is an integral component of the SolarShare Virtual Power Plant. The battery is the part of the SolarShare system necessary for your home to join the SolarShare Virtual Power Plant (VPP).


The actual installation process should take no more than two business days. One day to install the panels on your roof, the battery into your home and connect it to the Irish Grid. The second day – to commission your SolarShare system and connect with the VPP.

A Virtual Power Plant (VPP) connects domestic SolarPV and battery systems together into a community of clean energy generators. The battery technology used by SolarShare aggregates these domestic systems into the equivalent of a larger centralised power plant, not unlike Moneypoint. Moneypoint is the largest electricity generating power plant in Ireland burning coal to generate electricity. The plant’s generating capacity is equivalent to 200,000 domestic solar systems (4kWp).

By being part of the SolarShare VPP, you will be able to sell the excess clean electricity you generate back to the Irish grid and also participate in Load Balancing services with the main Irish grid. Both of these activities will produce additional savings for you.

A SolarShare system, depending on your configuration, will consist of the following components:

9-15 Solar Panels, a 5 kWh Battery as standard (expandable to 10 kWh) and an AC/DC Inverter to connect your SolarShare system to the Irish grid.

When you arrange a FREE online roof demo, a SolarShare Energy Consultant will take you through the process of sizing the perfect SolarShare model in order to maximize the energy generation depending on the size of your roof, its orientation to the sun and the average annual electricity consumption.

Your SolarShare system comes with a 2-year installation warranty. The solar panels come with a 12-year manufacturer’s warranty and a 20-year linear performance warranty. The Inverter and Battery each come with a 10-year warranty.

Once connected to the VPP, SolarShare will continuously monitor your system for optimal performance and maximise your income from the sale of excess electricity and balancing services.

You may qualify for a grant from SEAI of up to €3,000 depending on the size of the SolarShare system you purchase, and as long as you meet the following criteria:

– The energy rating of your home, after the SolarShare installation, is at least C, and

– Your home was built and occupied before 2011.

A SolarShare system installation requires an exemption from Planning Permission which can take up to 8 weeks to obtain. Your SolarShare Energy Consultant will take care of the process of applying for the Planning Permission exemption.

Your SolarShare system will last approximately 20-25 years. For the purpose of the calculations contained in the Compare Models page, we are using a figure of 20 years.

If you already have solar panels installed on your roof and you have a battery that stores the excess you produce, then SolarShare should be able to connect your system to the SolarShare VPP, although additional equipment may be required.

If you do not have a battery, then you should consider purchasing a battery from SolarShare for storing the excess clean energy you generate. Once we have installed the battery, we will be able to connect your system to the SolarShare VPP.

Being part of the SolarShare VPP does not limit you in any way for future appliances or electric vehicles that you may purchase. In fact, being part of the SolarShare VPP may offer you opportunities to avail of greater discounts on future appliance purchases based on the purchasing power of the SolarShare VPP community.

There is no long term contractual commitment required in order to be part of the SolarShare VPP. We intend to earn your long-term commitment by way of delivering a superior product and customer experience over the life of your SolarShare system.
