Solar Power System Calculator

Solar power system calculator. Learn how much renewable energy a system mounted on your roof can produce in a year. Which part of the electricity you can use yourself, and how this helps to reduce your energy costs.

We have been developing and implementing PV systems since 1996.

The first experience started in the Netherlands with an off-grid system. We gained a lot of experience in England, Germany. Now for several years in the Algarve Portugal. 

Experience with roof-mounted systems as photovoltaic projects in the open space — net-connected and off-grid projects. We cover a complete range of services. From the development and implementation of energy projects. To the sale of photovoltaic products, installation of Solar power system and technical management.

Since SMA launched its new product on the market, the Sunny Boy Storage 2.5 / 3.7 / 5.0 and the 6.0 series, it is desirable for private households to store the surplus amount of power from a PV panel system in Lithium batteries.

  • We offer permanent service on location.
  • Guarantee high yields.
  • Always working according to the latest technological standards.

We are just as flexible about the design of our services as our projects and what customers want. You will have the opportunity (perhaps necessity) of downsizing your electricity usage. Our system calculator show how large your home power system needs to be. Together with you, we develop a tailor-made solution for every situation.

Photovoltaic power system calculator

As an experienced company in the field in renewable energy we calculate the amount of energy that is necessary to keep your Electra bill close to zero. Solar power system calculator of your private PV system will give important factors as:

  1. How much square meter of photovoltaic boards.
  2. Simulates the power rating with sunshine hours per day.
  3. Amount of electricity generating in kWh per day.
  4. Based on experience in the Algarve Portugal.
  5. Surplus in kilowatt hour

Our specialism is on the territory of off-grid systems. We mainly work with the sunny boy storage and the sunny island.

SMA technology AG gives a great warranty and has an official service partner in Portugal. 

BYD lithium battery

Most used by us as battery storage, are the newest from BYD. This company has successfully expanded its renewable energy solutions globally with operations in over 50 countries and regions. Therefore also in the Algarve.


The market for electric vehicles (EV) has gained momentum globally in recent years. More and more countries are planning to move away from conventional cars with petrol and diesel engines. Also, the phenomenon of the vehicle to the grid is more and more a reality in the Faro region of Portugal. 

For electric car owners, our photovoltaic power system calculator may be extra interesting for you! To be ready for the future with vehicle to grid technology, without any extra costs, a second calculation with the EV integrated into the PV system will be made. To have the EV as a energy storage for your house. 

Sure you like to know in advance how much amp hours or watt hours is necessary to have the maximum range. One panel of 250 watts will not be enough! 

For 50 euro, we make a proper calculation from the delivered data. Or if you prefer, for an additional 25 euro we will visit, to investigate your situation. Of course if our calculation is converted into order, 75 euros will be deducted from the invoice.
