This is a form of self-consumption in which surplus energy (not self-consumed) from the installation in question is fed into the grid. The energy supply company is obliged to purchase this energy for which it pays a monthly compensation per kWh fed into the grid to the user, which is lower than the purchase price, in the form of a discount on the electricity bill. It is important to note that the electricity bill balance can never be negative.
Photovoltaic modules have a service life of up to 40 years, however, the operating guarantees for the main equipment are up to 25 years.
Generally, the maintenance needs in self-consumption installations with power ratings of less than 30 kW are minimal and are limited to sporadic cleaning of the modules with water. However, the monitoring tools offered by SolarTree, as well as the guarantees on its installations, will allow you to identify and resolve any operational problems.
In the case of residential self-consumption, the best tariff to optimise savings with your self-consumption installation is the regulated tariff with time discrimination in two or three periods. Generally, the time periods with the most expensive energy price coincide with the installation’s hours of highest production, while the periods with no production coincide with the cheapest time periods.
A PPA is a bilateral power purchase agreement usually signed between a generator and a consumer with a term of 4 – 12 years for a price agreed between the parties. It allows consumers to protect themselves from electricity price increases and price variability, thus facilitating economic planning, producing energy cost savings and improving the profitability of businesses. If the generator is a photovoltaic installation, then the consumer is also assured of the clean origin of their electricity.
Yes, at SolarTree, as far as possible, we propose equipment that will eventually be compatible with batteries
To make the most of the production of your self-consumption installation it is important to use electro-intensive devices such as household appliances and water purifiers at peak production times and on the sunniest days. Our monitoring tool will allow you to see the production, consumption and surplus discharge at all times so that you can define optimal consumption patterns to maximise savings.
There are currently grants, backed by funds from the EU Next Generation Recovery Plan, which are allocated by the autonomous communities and which, depending on each case, can cover up to 45% of the cost of an installation. In addition, there are rebates on property, construction and personal income tax. At SolarTree we will help you apply for and receive all these grants to maximise the profitability of your installation.
Yes, at SolarTree we offer you different financing options and payment plans that will allow you to see the savings right from the the start.
SolarTree offers you a monitoring tool that will allow you to check the operation of your installation in real time.
