FAQ

Yes.

Yes, Freesuns roofs are hail resistant. Our Solaris™ Classic, Premium Black, and Heritage tiles can withstand 40 mm hailstones. They are therefore HW4 certified according to the rules of the Association of Cantonal Insurance Companies (www.vkg.ch). Our VDiamond tiles can withstand 30 mm hailstones.

Noise is reduced by the weight of the tiles in the same way as with traditional terracotta tiles.

For more information, our technical data sheets are available here.

Yes. Freesuns tiles can withstand a load of 13,333 Pa for our Solaris™ Classic, Premium Black, and Heritage tiles, and 5,400 Pa for our VDiamond tile. In addition, because the tiles are smooth, snow slides off quickly after a snowfall, allowing the solar tiles to capture the sun's rays again.

Our solar tiles weigh 52.20 kg per m² for Solaris™ Classic, Premium Black, and Heritage tiles, and 40.53 kg for VDiamond tiles. Standard roof structures can support this weight without any special modifications.

Yes, you can walk on the roof. Our tiles are manufactured to high standards of quality and strength.

Freesuns solar tiles are made with two layers of glass, for a total of more than 7 mm thickness. Since 3 tiles are installed on top of each other, the whole is very resistant. The tiles are designed to last more than 50 years.

You can visualize the photovoltaic potential of your building on the website of the Swiss Federal Office of Energy.

When the sky is not clear enough to produce solar energy, the grid takes over. In these cases, instead of consuming the electricity produced by your solar tiles, you consume the one of your energy supplier, via the electrical network.

Our solar tiles are installed like traditional tiles, using the double-overlap technique. After special training with our team, roofers are responsible for the installation.

Our tiles are designed in Switzerland, in partnership with Swiss and European research institutes.

Like the vast majority of photovoltaic modules, our tiles are manufactured in China. We work closely with our long-standing Chinese partner to ensure high manufacturing quality.

Yes, the installation is designed for this purpose.
If you decide to install battery storage, the batteries will have priority over resale to the grid.
If you don't have batteries, all surplus electricity is automatically sold back to the grid.

A solar roof allows you to produce more than you consume, and this during a good part of the year. Nevertheless, in winter, the production will not allow you to cover all your needs. Our customers with the most efficient roofs and storage batteries cover up to 80% of their annual needs.

There are several financial programs that allow you to reduce the amount of your investment.

The federal subsidy PRU (Petite Rétribution Unique - Small Single Retribution)
The federal government supports independent producers of photovoltaic energy with a one-time payment. For installations of up to 100 kWp (approx. 550 m²), we speak of the Small Single Payment (Petite Rétribution Unique - PRU). It consists of a single payment of financial aid. The institution in charge of paying this subsidy is Pronovo (www.pronovo.ch). The Freesuns team can help you apply for it.

How to calculate the amount of the federal subsidy (PRU)?
The PRU is up to 30% of the investment. It consists of a basic contribution and a variable contribution depending on the installed capacity. Both contributions change over time. The amount of the PRU depends on the commissioning date, the power and the type of installation (added/integrated). Pronovo has set up an online calculator to facilitate the calculation of the PRU for your photovoltaic project: https://pronovo.ch/fr/services/tarificateur/.

Other subsidies
Some municipalities provide additional funding: check with the municipality where the building is located. All subsidy programs of the federal government, cantons, cities and municipalities are listed here. 

Tax deduction
In case of renovation, you are likely to be eligible for a tax deduction. We recommend that you consult your trustee on this subject.

The delivery time is about 20 weeks, after signing the contract, and as soon as the first deposit is received.
