The free roof planner from MaltaSolar.mt. Enter your address, place panels on your own roof, see what they should generate, and send us the design for a quote.
The planner is provided by OpenSolar. Design requests you make in it — your address, the layout you draw and, if you ask for a quote, your contact details — are processed by OpenSolar on our behalf and passed to MaltaSolar.mt so we can reply. See our privacy notice. Its output and savings estimates are OpenSolar’s model, not our calculator.
SpecYourSolar is the free roof planner from MaltaSolar.mt. Type in your address in Malta or Gozo and the planner loads a satellite view of your roof. Place panels on it where they will actually go — around the water tanks, the stairwell and the parapet — and it shows the size of the system you have drawn and what it should generate. If you like the result, request a quote from inside the planner and the design comes straight to us.
It is a good way to answer the first question most people have, which is simply how many panels fit. Most Maltese roofs are flat, so the frame sets the tilt and the direction, and what limits a system is usually space and shading rather than which way the house faces.
A satellite picture is not a survey. It cannot tell how strong the roof is, how tall the neighbour’s tank is in the afternoon, or whether a building is scheduled. On a scheduled building, or one over 75 years old in a conservation area, panels must stay within the building envelope and must not rise above the parapet; elsewhere rooftop PV is permitted development under Class 1(iv) of S.L. 552.08 if it complies with DC15 (REWS Manual of Procedures, November 2025). The free roof survey checks all of this before anything is ordered.
For a second opinion on output and savings, put your panel count into the System size tab of our calculator. It uses the European Commission’s PVGIS yields for Malta — about 1,668 kWh per kWp a year facing south at 32°, 1,476 laid flat, 1,376 facing east and 1,393 facing west — and the Enemalta tariff, all cited on the page. The 2026 REWS grant closed to applications on 12 September 2026; a further round was announced but not detailed, so the calculator starts without a grant, at the €0.15 per kWh feed-in tariff for 20 years.
