Photovoltaic kit or sun installation: for what do you use?

When you plan to buy solar panels as a production of electricity of renewable origin, it is difficult to make your choice because the offers are multiplying on the market. Which photovoltaic kit feeding a camper or boat? An autonomous sun kit for the car -it, in what conditions and for what autonomy? 100W or 900W, 12V or 220V, what power and what tension? Turnkey photovoltaic installation or kit to assemble, how to choose? Battery, converter or inverter: which equipment to buy? For a purchase in adequacy with the desired use, Solar Land explains and guides you.

To choose it well: determine your needs.

When you buy its sun kit, 1^era The step is to direct its objectives: why invest in photovoltaics? The self -consumption or sale in the obligation to purchase EDF of EDF, the purchase of some lighting and camper campers or the desire for energy autonomy at home, the characteristics of photovoltaic kits must be in line with your electricity needs.

A photovoltaic kit for the nomadic house or isolated site: how to choose?

The offer of the Solar Kit by boat, camper, chalets and huts is large and for a good reason. It responds perfectly to the problems of these buildings: at sea, traveling or on an isolated site, access to electricity is limited and solar panels are a great way to access it.

Note : The autonomous kit can also be used to provide garden lighting, an electric gate or even a shed. Solar energy in this hypothesis is a good alternative to the delivery of electricity remote from the house. Limited power is sufficient in this context.

The offers of sunscreen for campers, hut or garden are sometimes clearly identified and presented directly in this category. Concretely, by boat, camper or isolated chalet, he must meet the following criteria:

• An autonomous sun kit that includes photovoltaic panels, a regulator, wiring and adequate fixing – for the boat tree or the roof of vehicles or habitats. When it is intended to provide home devices at 230 V-Shash, refrigerator, TV, Pump-it must also include a 12 V / 230 V or 24 V / 230V converter.
• Sufficient energy to cover electricity needs. Power is expressed in Watts (W) or Kilowatt (KW) and represents the energy production capacity of the panels, which also depends on the site of the site. The concept of power is the most important criterion of choice: it is important to determine the devices of your nomadic or isolated habitat upstream, then trust the suppliers’ indications.

Recision on the sun earth: 30 photovoltaic panels installed overlapped

Note : Some online suppliers offer hybrid photovoltaic kits, including a wind turbine to increase electricity production thanks to the energy force of the wind. The option can be considered based on the weather conditions of the destination site.

Last element to choose your autonomous photovoltaic kit well, the price! Anyone who is not expensive, however attractive, can hide insufficient power to cover your energy needs, also a quality of mediocre materials. On the contrary, if it is too expensive, it represents a disproportionate investment regarding the amortization possibilities. Be careful to calculate the profitability of the purchase, except to trace a line on the return on investments …

To obtain its electric autonomy or generate income: sun installation.

If your project is autonomous at home to save on electricity bills or generate additional revenues from the sale of green electricity to the EDF solar purchase obligation, a more powerful photovoltaic kit is required. The necessary equipment and installation techniques also differ:

• The objective of the car -consuming or sales provides for the purchase of powerful solar panels in sufficient number, with which to associate a converter – or inverter – capable of converting the continuous current by alternating the current alone compatible with the network. To estimate the necessary power, it is wise to base yourself on your declaration of electrical consumption. In order to cars -consum, to benefit as much as possible from electricity produced in optimal sunshine conditions, it is also possible to buy an optional storage battery: this accessory allows you to store excess electricity with a good weather to return it in unfavorable conditions.

Note: The prices of the solar panels are falling, the 9 kW photovoltaic kit is acquired at a higher price but offers better possibility of profitability than the 3 kW, for example.

• Roof sirprosition, installation on the ground or system of a solar refuge, the installation of your photovoltaic panels requires a connection to the distribution network and the creation of previous administrative procedures. In these conditions, it is wise to contact the offers of «turnkey» photovoltaic kits.

Ready for the ascent or turnkey service: should we save on installation?

The small sun kit ready to be climbed is perfectly used for use on nomadic habitats or on the isolated site. The relatively summarized connections and the fixings provided allow to make the installation provided alone, you are a minimum handyman. When the solar panels are intended for the car -with the case at home, on the other hand, implementation is more technical. Fixing in the coverage or facade, the connections of the elements between them and the connection to the network really require clear skills. For this, it is preferable to call professional roofs and electricians, at the risk of making mistakes that lead to the ineffectiveness of the installation or other harmful consequences – in particular the lack of waterproofing of the roof.

Whatever your solar electricity, it can be wise to ask the seller for advice to make sure to buy the right photovoltaic kit.
