A question?

Installing a solar panel on your balcony does not require any building permit or prior work authorization. However, it is necessary to check that the installation of this photovoltaic module does not contravene the co-ownership regulations. As a tenant, the same regulations apply. You can absolutely install a Sunflower kit if nothing prohibits it in the co-ownership regulations. When purchasing a Sunflower kit, you will simply need to declare it to your supplier by following our guide (hyperlink guide).

Generally speaking, the installation of a Sunflower kit on a balcony railing must comply with current safety standards and must be done while respecting the precautionary measures which appear in its installation guide (hyperlink guide). If, however, you decide not to place your kit on a balcony but on the ground at a height greater than 1m80 from the ground of your building (on your roof for example or attached to a facade), installation will require a prior request to the town hall.

If you are also a fan of self-consumption with Sunflower, it is in fact possible to expand your installation by adding one or more kits to your current installation. However there are limits to respect, the total power of your kits cannot exceed 3 KWp if you do not wish to take additional administrative steps. A total power of 3 KWp is the equivalent of approximately 6 Sunflower 440W kits.

Our Sunflower 440W kits generate on average 625 Kwh per year for a station installed with a southern exposure in the PACA region. Depending on your electricity rate, this translates into around €170 of electricity per year. However, even if at Sunflower we guarantee you a quality product, we cannot guarantee ideal weather conditions all year round. Your total savings will therefore fluctuate depending on your solar exposure and your local electricity rates.

Sunflower kits require minimal maintenance. It is generally advisable to check the fixing of the panels in the event of damage as well as to keep the panels clean by cleaning any debris that may cling to them.

Thanks to the Sunflower guarantee, your kit will be automatically replaced in the event of defects. Our after-sales service teams are available to assist you if you notice an anomaly when your order arrives or throughout the life of your kit.

Yes, a Sunflower kit can generate electricity even on cloudy days thanks to the low-voltage technology of our microinverters and our high-performance monocrystalline panels.

Absolutely. The Sunflower kits have a modular inclination which allows you to always have the perfect angle to maximize electricity production. A good seasonal tilt can significantly increase your production by over 20%! This is why at Sunflower we developed our Sunguide (product link), the accessory that allows you to always have your kit at the ideal angle without thinking!
