SOLON FAQs

General customer questions:

Where can I buy SOLON products?

There are several options available. We recommend that you contact us directly so that we can learn about your project. We can either plan and implement the project ourselves or forward it to one of our specialist partners, depending on the type and scope of the project. In either case, we will find the best solution for you!

Who performs the installation of SOLON products?

Again, there are several options available. We recommend that you contact us directly so that we can learn about your project. We can either plan and implement the project ourselves or forward it to one of our specialist partners, depending on the type and scope of the project.You will always get everything, from planning to construction and monitoring, from one source.

What do SOLON products cost?

Each project is handled individually, therefore there is no standard price list. However, we will gladly provide you with an offer that is adapted to your needs. Why not arrange a personal discussion? Simply contact us. We are looking forward to meeting you!

What delivery times can I expect?

SOLON is able to respond to your needs very quickly. However, our delivery times are also determined by the demand and the contract situations of our suppliers. When the requested product is in stock, we will obviously deliver it immediately.

What types of solar cells are used in the modules?

Only top-quality poly- and monocrystalline cells are used for SOLON modules. We only source from selected manufacturers to ensure consistent quality at all times.

What requirements does my roof have to fulfill to qualify for a PV system?

Most roofs are suitable for PV systems. Your roof should not be in the shade and must be in good condition, i.e. it should not need renovating in the next 20 years. The roof must be evaluated by a structural engineer for safety reasons.

Which orientation (south, east, west) is best?

In general, the best yield is achieved when your roof is oriented toward the south. Orientation toward the south-west or south-east is nearly as good. However, orientation toward the east and west may also provide attractive returns, depending on the location of your house and the pitch of the roof.

Do modules in SOLON PV systems have to be serviced or maintained?

Modules used in SOLON systems require minimal maintenance. We recommend cleaning the modules once a year for the first 5 years, and twice a year for the remaining life of the modules, depending on the air quality and regional environmental factors to produce optimum yiels

Solar technology FAQs:

What is photovoltaics?

Photovoltaics is the direct conversion of solar energy into electric current using solar cells.

How does photovoltaics work?

When light strikes a solar cell, it creates an electric voltage between the surface facing the light and the surface turned away from the light. When the electric circuit is closed, electric current flows. (Source: DGS)

What does a solar power system consist of?

The base unit of a PV system is the solar module. Several modules are connected to a solar generator. Because the generator creates direct current, it requires an inverter to convert the direct current into alternating current for standard electrical applications. The electricity is then fed into the public power grid via a meter.

What is a module made of?

The main components of a module are solar cells. Several of these cells are combined into one module. The module is then laminated in a plastic layer and framed between a glass cover plate and a rear panel.

What steps are involved in the value creation chain for module creation?

Silicon raw material is derived from silicon-rich rock (e.g. sand). The silicon is melted to form blocks known as ingots. The ingots are then cut into paper-thin discs called wafers. The wafers are then used to make solar cells that form the main constituent of module production.

What kinds of PV systems are there?

In general, there are two different kinds of systems:

1. Structure
The most common type of mounting is the rooftop installation. This method makes particularly efficient use of space. Further mounting options include rooftop integration and building integrated systems.

2. Freestanding
Freestanding plants are systems that are mounted on the ground. The modules can be fixed or installed so that they track the sun.

How is a photovoltaic system different from a solar thermal system?

Instead of generating electricity from sunlight, a solar thermal system generates heat in the form of hot water or heat energy.
