Your own installation

Owning your own solar energy installation

Owning your own solar energy installation could be a very interesting option. But where should you start, what do you need to take into consideration, what information is available and how do you start up the whole process? Solinq can tell you all about it, and can take all the work and trouble off your hands.

We can arrange everything

All we need to do is measure your roof and choose a date that is convenient for you to start the installation, once you decide to go ahead with the project. You have nothing to worry about, we will arrange everything!

We use professional software packages to make detailed simulations of your yields. This allows us to put together an optimal package so you are assured of a solar installation that makes maximum use of your roof and that yields the highest possible returns.

You have nothing to worry about

Solinq will apply for grants, calculate the payback period, take care of the entire assembly and the link-up to the grid of the current energy supplier, install the necessary meters using CertiQ, mediate in manufacturers warranty cases, etc., etc.

The panels are maintenance-free, so during the life cycle of your system you will not need to worry about service costs.

With the exception of listed buildings, there are no building permit requirements for solar installations. However, we do recommend that you notify the council that you intend to install a solar system.

What is a Watt Peak (Wp)?

Solar panels are labelled with a power output expressed in Watt Peak. This is a figure that represents the nominal power of a panel and specifies how much power output a panel achieves under full solar radiation. The latter is a relative concept, which depends on the positioning of the panels and the country you live in. A certification is used as a benchmark to make all solar panels comparable. In the Netherlands, a full sun situation accounts for 85% of the standard test conditions. A 100 Wp solar panel generates 85 kWh in the Netherlands, if the solar panels are south-facing and at an angle of approximately 30°.

How large should my installation be? An example:
Suppose you use 2700 kWh* per year, then a total of 2700/0.85 = 3176.47 Wp is required.
This figure, divided by the Wp of the panels (e.g. 230 Wp), is the number of panels you will need; in this case 14 panels.
* Based on long-term averages.

What does it cost and how long will it take to recover the costs?

The payback period for your solar system depends on a number of factors, including the acquisition costs, subsidies and energy yields.

Example 1*
Investment:

Example 2*
15-year fixed annuity mortgage of €10,750.00 at 4.5% interest and 42% mortgage interest relief.

Gross monthly overheads:  €89.17
Net monthly overheads:  €72.24

2975 kWh/12 months = 248 kWh per month
248kWh x €0.526 = €130.45

Annual gain: (€130.45 - €72.24) x 12 = €698.52
