1 or 2 panels, how much power do I need?

As a rule of thumb, in Southern Europe households of 1-2 people should be fine with 1 Performance panel, while 2-3 people probably need 2 panels. If you have many appliances connected, as well as your water boiler or air conditioning, 2 panels are recommended. Use our Savings Calculator to see how much you can produce at home with different types of kits.

The most important factor to influence production is how much sunshine you can get onto your panels for the longest amount of time during the day. See the infographic for the effect of orientation on production.

Check your power bill
To understand your consumption, check your last power bill for kWh consumed per month. As an example, if your yearly consumption is of 3.000 kWh, a Performance 800 can reduce this by 1.638 kWh with good orientation and angle. In this example, it is also very likely that you will use all your kit's power, with almost no surplus energy. This minimizes the earnback time of your investment.

20, 60 or 90 degrees - What mount do I need?

In Europe, solar panels work best if positioned at a 30-35 degree angle. While that happens to be the case on many pitched roofs, it's hard to achieve on a balcony or wall installation.


To understand the impact of the angle, compare the production of a south-facing Performance 800 kit in the infographic.
An horizontal installation's production in summer will be almost 3x that in winter, while in vertical mount in winter you will produce almost 3x as much as in summer. At a 60 degree angle production is almost equal among the months.

Balcony railing

To install a Performance kit on your balcony railing, we recommend you do this at no more than 4m of height. Performance panels weigh 24kg each, and winds in height can develop a sail effect. Our balcony mount kits come with heavy duty clamps that can hold 300kg each. Each panel is held by 2 such clamps for maximum stability and safety. You can chose between a vertical mount of 90 degrees, or a triangle mount with a 60 degree angle, increasing production.

Wall mount

To fix your panels against a wall, our kits come with the necessary screws and dovels. You will need to drill holes and fix the mounts safely. For wall mount, we have a vertical 90 degree structure, as well as a triangle mount with a 60 degree angle, increasing production.

Flat surfaces

To mount your panels on a flat surface (like your garden, garage roof or pergola), we offer a 20 degree mount structure with rubber bases. The mount is extremely easy to set up. See the video further down on this page. Should your panels be exposed to strong wind, you can add concrete blocks to the mount for additional protection (not included in the kit).

Any other surface

If you have your own solution on how to mount your kit, get your kit without a mount. You can fix the panels with a mount you already have, or in any form you see fit. Keep safety in mind, and assure a stable and solid installation that assures long time production.
