9 Clever Uses of Solar Energy at Home

Eversource Rate Spike Hits CT Pool Owners: Solar Power Provides Lifeline

As we seek greener and more cost-effective solutions for our daily energy needs, solar energy at home stands out as a compelling option. Embracing solar power reduces your carbon footprint and offers significant savings on energy bills. Here are nine innovative ways to harness solar energy at home in Fairfield, CT, to transform how you live and interact with your environment.


1. Solar Water Heating

Harnessing solar energy at home for water heating is one of the most practical and beneficial uses of solar power. Solar water heaters use solar panels, often called collectors, installed on your home's roof. These collectors absorb solar energy and convert it into heat, which is then transferred to water.


How Solar Water Heating Works

Solar Collectors

The solar collector installed on the roof is the most visible part of a solar water heating system. These collectors come in two main types: flat-plate and evacuated tube. Flat-plate collectors are typically more cost-effective and sufficient for most residential needs, while evacuated tube collectors are more efficient and can function more effectively in colder climates.


Heat Transfer Fluids

In colder climates, where freezing is a concern, solar water heating systems use a heat transfer fluid, such as antifreeze, instead of water. This fluid absorbs heat from the sun in the collectors and then passes through a heat exchanger to warm the water in the storage tank without freezing.


Storage Tanks

After your solar energy at home heats the fluid, the heat is transferred to water stored in a tank similar to conventional water heaters. Some systems have integrated collector storage (ICS) or thermosyphon systems, where the tank itself is part of the collector on the roof, using gravity and natural convection to heat the water.


System Controllers

Most modern solar water heating systems include controllers that monitor temperature differentials between the tank's and collector's water. When the collector is hotter, the controller activates pumps to circulate the fluid, maximizing heat absorption.


Backup Systems

Most systems are equipped with a backup heating source for days when solar gain is insufficient, such as during extended overcast weather. This backup can be powered by electricity, gas, or other fuels, ensuring that hot water is always available.


1. Solar Panels for Electricity
