What Can Solar Energy Be Used For? 17 Ideas for Daily Life.

Searching for ideas on how to use more renewable energy in your daily life? Here’s a comprehensive list of 17 ways solar energy can be used at home or in business; including the most common solar powered products to help you live more sustainably.

One thing to note is that solar technology is not a new thing. Actually, harnessing solar energy has been around for centuries now. The first recorded evidence of solar energy usage is dating back to 700 B.C. Back then, people would focus sunlight using magnifying glasses to make fires bigger [1].

Why Use Solar Energy?

Today, solar energy is not a green dream anymore. Rather it’s a technology with a broad application area. From powering our homes and cars with electricity generated from the sun to use it to power consumer electronics and devices using solar energy has many advantages including:

  • Helping to slow climate change and reducing pollution. Using solar energy is good for the environment because it does not involve the burning of fossil fuels to create electricity. Therefore it reduces greenhouse gas emissions, noise pollution, and pollutants that are harmful to our health.

  • Save money by lowering your energy bills. Reducing the need to draw power from the energy grid and instead of using the power generated for free by the sun can lead to savings of hundreds or thousands each year in electricity and gas bills.

  • A way to use less water. Solar power does not pollute the water, and it also does not use as much water, compared to the traditional way electricity is produced.

  • Solar energy technologies are a good investment. The global Solar energy industry has been growing rapidly in recent years creating jobs and supporting local businesses.

    Currently, Europe dominates the market due to government policies.  The industry is estimated to continue growing for the next decade and be a market worth over USD $220 billion by 2026 [2].

  • An opportunity to receive discounts, credits, and/or rebates. While the initial cost of installing solar may be high, over the medium to long term it gives a positive return. Today many states or areas offer tax credits, grants, or rebates that may be available to you to offset the upfront costs.

    There is also a large Solar Power market where you can also ‘make’ money by feeding the extra solar energy you don’t need or use back into the grid. In return, the power company or utility company will ‘buy’ this energy by crediting your bill/account. This is known as net metering.

Clean energy generation is a key application of solar energy. It has gained a lot of momentum in recent years. There are two primary technologies to generate electrical power from solar energy:

  1. Solar Photovoltaic (PV) System
  2. Concentrating Solar Power (CSP)

Solar Photovoltaic (PV) System

Solar PV panels convert sunlight into electrical energy, generating a direct current (DC). This direct current is then sent to an inverter for conversion from DC to alternating current (AC) which can power your entire house from running your heating, charging your devices to providing power for your appliances.

A drawback of solar PV energy is that it can generate electricity only during the day. To overcome this, homeowners use a battery bank with their rooftop solar PV panels to store electrical power.

Energy engineers and trained technicians can help set up a solar PV system for your house or office using Software to simulate and model solar PV systems which can also estimate the costs of designing a solar PV system.

According to EnergySage, the average installation cost for a 5 kW system in the US is $12,500 to $17,000. Though Government subsidies and rebates can cut your total expenses by 50 percent! 

Concentrating Solar Power (CSP)

A great way to cut down on your energy use is by using solar energy to heat or warm water.

Solar water heaters use the heat energy from the sun, converting it into thermal energy to heat water. They can replace the traditional expensive gas & electric water heaters in your house.

There are two types of solar water heater systems:

  1. Active Water Heater Systems
  2. Passive Water Heater Systems

Active Water Heater Systems

These systems use pumps for circulating water between thermal collectors and storage tanks.

Passive Water Heater Systems

Passive hot water solar system uses a natural circulation method instead of mechanical pumps. Thus they are cheap and less efficient as compared to active water heater systems.

According to the US DOE, these systems have a payback period of 5 to 10 years, with installation costs ranging between $1000 and $4000 USD depending on the system, location and capacity required [Reference: homeadvisor.com].

#4 Solar House Heating

The energy from the sun can be utilized for space heating as well. Solar space heating systems can heat your entire house or office in the winter, on cloudy days, and even at night. 

The warmth from either water or air is moved throughout the house. It can be through radiators or tubes used in underfloor heating. Solar space heating requires a large investment. Thus they are commonly used in businesses or commercial applications.

Solar heating technology is a great way to go if you’re serious about using solar energy in your house.

#5 Solar-powered Pumps

Solar-powered pumps are useful in areas where grid electricity is not accessible or practical. 

Examples of pumps include solar-powered water pumps to deliver drinking, livestock, and irrigation water. The oil industry has also started to use solar power for pumping systems because of their remote / off-grid locations and increase in environmental awareness. 

Active water heater systems can save you a lot of energy. To pump hot water, they still need electricity. So rooftop solar panels can help you power those pumps and save a large amount of electrical energy.

Many applications of solar-powered pumps require a battery bank with a solar PV system for energy storage to let you use electrical energy on demand.

#6 Solar Lighting

Solar energy can also be used to heat swimming pools.

According to the US Department of Energy:

“solar pool heating is the most cost-effective use of solar energy in many climates.”

The mechanism of swimming pool solar heaters is simple. The water of the pool circulates through a thermal collector. The water is heated by the thermal energy from the sun and then pumped back into the pool. The concept of heating pool water is almost the same as solar water heating systems.

According to US DOE, Swimming pool solar heaters cost around $3000 and $4000 with a payback period of anywhere between 1.5 to 7 years.

Another option for heating the swimming pool using solar energy is using a solar blanket. The floating solar blanket is a passive heating device. It works simply by absorbing the sun’s heat and transmitting it to the water.

#9 Solar Ventilation and Cooling

Solar energy can also be used to power attic ventilation fans or air conditioning systems. They can reduce energy costs associated with heating, ventilation, and air conditioning (HVAC) systems during the summer.

Traditional exhaust fans use a lot of electrical energy. To overcome this, you can buy a self-contained solar roof vent fan. It comes with a small photovoltaic panel attached to the top of the fan.

The solar panel powers the electric DC motor responsible for the fan’s operation. With a built-in solar panel, there is no longer need for a secondary electricity source.
