Solar energy is free. However, it is not available 24 hours a day. Thus, a solar water heating system should normally require a backup heating system. The most common backup used in the market are electric storage water heaters.
Solar energy can be maximized for water heating use by providing enough collector panels and large enough hot water storage. With limited roof or surface area dedicated to solar panels, this solution is not usually practical.
Our SolarActive Water Heaters harness the sun's energy to provide hot water. This system can drastically reduce your water heater operational costs, saving you money. SolarActive flat solar collector panels are especially suited for the Philippines' tropical sunlight.

The performance of the Solar-heat pump water heating system in Shangri-la Edsa is excellent. It is not free as pure solar energy. It never is. But using heat pump as backup, it's as close to free as it gets. Operating cost is reduced by more than 80%. Now all steam boilers of Shangri-la Edsa are scheduled to be shut down, except for a small capacity to serve steam and high temperature requirements for kitchen and laundry.
