In a smart green home, there is the option to make use of the sun to generate free electricity. With a grid-tied system, there is a back-up power supply in the event of a shortfall.
Using a heat pump, combined with a linked-loop hotwater system, hot water is immediately available in the home. Heat pumps are very efficient and need little energy to heat water. Costs are therefore reduced.
In a green home, air-conditioners and heaters are not required. With Hydronics Radiant heating and cooling, the home is fully temperature controlled at minimal cost.
Using rainwater for watering the garden, for the washing machine and to flush the toilets also saves on the monthly water bill.
And using low-flow shower heads and taps saves on water consumption, resulting in great savings for the homeowner.…
Here are some renewable resources that are used –
Bamboo: This material is sustainable and an alternative to wood. It has a lower impact on the environment but lasts just as long. Bamboo is used for flooring and counter tops, amongst other uses.
Rainwater: A green home requires a sustainable water supply. The cheapest rainwater harvesting methods are actually the most efficient, but the advice of an expert is recommended when installing such a system. A vendor with an excellent reputation provides us with the best rainwater harvesting system.
Solar energy: We’ll need to consider our needs carefully. Photo-voltaic solar panels are the most obvious method for reducing reliance on the grid – we’ll need to ask ourselves how much energy is needed for all our appliances. …
While we may think that installing photovoltaic solar panels is expensive, they are actually quite affordable. The cost has come down considerably as the demand for alternative energy sources has increased. Today, they cost half as much as they did in 2008 and the solar market has increased substantially.
When solar panels are fitted onto the roof, they are positioned in such a way as to maximise the harvesting of solar energy. Throughout the day, this photovoltaic system will harvest as much solar power as is needed for the home. Anything over and above what is used will be stored in batteries. These batteries, if full, are able to supply the home’s power needs for approximately one whole day.
The sun will run your home’s power while it is shining.…
It’s the ultimate dream for every homeowner—being able to produce enough electricity to run your home without ever relying on the grid. The benefits to homeowners are twofold. First, it can significantly reduce your monthly electricity bill. Second, you’ll never be without power. Even if the grid goes down, your appliances and lights will carry on working.
Existing homes can also be retro-fitted with a photo-voltaic system, although this may incur some additional costs. We’ll look at what’s involved, how the system works and what costs and saving you can expect from using such solar power.
What is a photo-voltaic system?
Essentially, photo-voltaic means harnessing the power of the sun and converting it into electricity that can be used to power your home.…
What’s the first thing that springs to mind when you hear the words ‘solar power’? Do you picture an eco-friendly home with solar panels on the roof? You’re not wrong, though there are some other ways to harness the power of the sun for your home. Using solar power can help you reduce your reliance on the grid and put cash back in your pocket.
Solar power is a versatile and sustainable source of energy. Here are some unusual ways you can use it to power your home:
Solar water heaters
Heating water for your home accounts for a significant portion of your monthly energy bills. A family of four needs a lot of hot water for their daily cleaning, bathing and cooking needs.…
Despite the lack of rolling blackout in recent months, South Africa is still facing a power crisis. Investing in eco-friendly homes with photovoltaic solar panels is one solution to the problem. Though these homes are more expensive than traditional ones. If you’re a first time home buyer, does it make sense to splurge now and to save in the future? Here’s everything you need to know about owning a photovoltaic solar powered home.
The advantages of photovoltaic solar power
Beyond the obvious savings on the monthly electricity bill, photovoltaic solar power makes sense for a number of good reasons. Eco-friendly homes that run on photovoltaic power systems include the following benefits for homeowners:
Never run out of electricity
As long as the sun is shining, we’ll be able to run the home.…
