2. How Many Solar Panels to Heat
Your Water
• Many households have to pay huge amounts
of money on the energy they use for heating
water. A green and more affordable alternative
is installing a solar water heating system that
uses the free, clean energy of the sun to heat
water for the entire house.
• A solar water heating system is comprised of
the following components:
• The collectors (the solar panels that collect
solar energy)
• A hot water tank to store the heated water.

3. • It is advisable to have a boiler or other kind of heater that
can heat the water when the solar system is not able to (for
example, at night or in the cold seasons).
• Before calculating how many solar panels you need to heat
the water your house uses, you have to make sure solar
energy is the most suitable solution for you. In fact, the
number of solar panels matter less than the insulation of
your house (the amount of sunlight it receives). For a solar
system to be effective, your house has to enjoy enough
sunlight for the panels to create the necessary energy.

4. How to decide if a solar energy water
heating system is for you
• If you live in a sunny area, that enjoys a warm climate all year
round, then you are the most suitable candidate for installing a solar
water heating system. Make sure you have enough space to install
the solar panels and the water tank. Also, you have to position the
panels so that you maximize the amount of sunlight they receive.
• One thing you should take into consideration is the fact that the
solar heating system’s efficiency will vary, depending on the weather
and temperature conditions.
• The system will certainly do a better job in the summer than in
winter. That is why it is intelligent to have a back up water heating
method for unfriendly weather periods.

5. How many solar panels are necessary to
heat the water for a household?
• Several factor need to be considered when calculating the number of solar
panels and the size of the heating system:
• average hot water usage for household member
• the insolation in your area
• the weather and climate
• the size of the panels and of the water tank.
• A person uses between 40 and 60 liters of hot water every day. Roughly, a 4
member family would need about 2 to 3 solar panels and a water tank of
about 200 liters. The hot water can last for a few days, because of the
thermal qualities of every water tank.
• If you decide to install a solar water heating system, you should first
calculate the average amount of hot water your family members use, and
then decide the size of the water tank and of the corresponding solar panels.
