Solar Heating For Pools

If you have a heat exchange heated pool, you know that this heated pool is a sizable amount on your electricity bill. Maybe it is time to consider solar heating. Solar heating will have a positive effect on you bank account.

Solar heating systems for pools.

When most people think of solar energy, they normally associate this with large photo voltaic structures that convert sun rays into electricity. However, the sun can also be used for heating pools and geysers. By using solar heating to heat your swimming pool, you can be sure that your morning swim will be comfortable and easy on the pocket.

How to make solar heating for your pool more effective

In most areas the temperature at night will cool down, thereby cooling the pool slightly. A good investment will be a pool cover, this will retain your heat and keeps your pool cleaner. (More time for you to enjoy your heated pool.)

Pool solar panels are normally installed on the roof to capture the most of the sun. The black solar panels consist of tiny tubes. The pool water while pumped through these panels will collect heat which is transfer ed to the pool water.

The use of solar heating heating pools is a time tested technology. You will probably know many pool owners who use the sun to heat their pool. The initial investment has a fast payback time due to saving in electricity use.

So in short, a solar heated pool is a great economical and eco-friendly investment, you will be the envy of your friends with your heated pools.

Solar energy technology road maps

The department of energy is busy developing a solar energy technology road maps.

The South African Solar Energy Technology Road Map (SETRM) is being developed to provide a comprehensive, aligned, achievable and time bound strategic plan that will help guide: policy and regulatory development, industrial strategy and related investment, education and skills programme development, innovation, research and development; and the overall diffusion of solar technologies in the country, and given the country’s significant regional impact, in the broader Southern Africa region.

The objectives of the Solar energy technology road maps are:

To develop a clear, comprehensive, and prioritized implementation plan (i.e. roadmap) for the development and diffusion of concentrated solar power; solar photovoltaic technology (ies); solar heating and cooling technologies; and related R & D in South Africa toward reduced energy use, carbon emissions reduction; distributed electricity generation, expanded independent power production and electricity supply to the national grid, and the reduction of reliance on carbon fuels.

US invests R5.4bn in SA solar power

US government development bank, Overseas Private Investment Corp (OPIC), will invest up to R5.4 billion ($400 million) in a solar thermal plant in SA.
The 100MW Redstone solar project, developed by California-based SolarReserve and Saudi Arabian electricity producer ACWA Power, will be situated in the Northern Cape and provide electricity to over 200 000 homes during peak demand once complete.
“In itself, [the project is] not that big,” considering SA has a peak power demand of approximately 35 000MW, says Chris Yelland, energy analyst and MD of EE Publishers.

Yet small-scale renewable energy projects are relatively quick to deploy, and a large number of small energy projects affords SA’s energy sphere more flexibility and less risk than relying mostly on large-scale plants, which often take longer than expected to develop, pose greater risk to SA’s power grid if they encounter complications, and are too expensive for private investors to finance, Yelland continues.

Commerzbank Sees 10 Percent Drop in Renewable Energy Finance in 2015

Commerzbank AG, Germany’s second-largest lender, expects a 10 percent decline in renewable energy financing deals after a spate of offshore wind projects moved ahead last year.
The lender this year plans to arrange new loans with a volume of about 750 million euros ($837 million), focusing on Germany, western Europe and the U.S., Ingrid Spletter-Weiss, the head of bank’s renewable energies unit, told reporters on Tuesday in Hamburg. This follows a surprisingly strong 2014, when wind projects were accelerated to nail down subsidies before the German government cut aid, she said.
“You need to really fight for good projects now,” Spletter-Weiss said. “We are seeing much more competition, in particular in the offshore market, which many players still didn’t dare to enter last year.”
Europe has more than 91 percent of the world’s offshore turbine installations. The region’s industry needs 10 billion euros by the end of 2016 to expand by about 20 percent, the European Wind Energy Association (EWEA) estimated on July 30.
Commerzbank’s renewable energy loan portfolio stood at almost 4 billion euros at the end of last year with onshore wind still accounting for a 70 percent share. The share of offshore wind, which made up 5 percent of the total volume, will probably increase to 10 percent in the coming two to three years as growth in the onshore sector slows, Spletter-Weiss said. …

Renewable Energy benefits seen at R4bn in 2015

South Africa saved R4 billion ($310 million) in fuel and by avoiding blackouts in the first half of 2015 due to renewable-energy projects, according to a study by the Council for Scientific and Industrial Research.
From January to June, 800 megawatts of wind and 1 gigawatt of solar photovoltaic power-generation saved about R3.6 billion in diesel and coal-fuel costs, according to the Pretoria-based center. During 15 days in the period, renewables either prevented or limited rolling blackouts, the study showed.

South Africa’s state-owned power company Eskom has imposed rolling blackouts almost every other day this year as it struggles to meet demand. The government’s five-round program of clean-energy tenders has awarded more than 5 000 megawatts of projects since 2011.

How to save energy

Saving energy and reducing fuel consumption has many benefits. Not only does reduced energy and fuel consumption save you money, it also saves valuable resources which can be depleted. Another advantage of saving energy is less impact on the environment and preserving valuable resources.

Reduce electricity consumption with these easy tips

  • Buy Energy Star qualified appliances, or A or B rated appliances and lights. These are the low energy using appliances.
  • Improve the insulation of your property, to make it cooler in summer and keep it warmer in winter. Les heating and cooling will be required which saves electricity
  • Turn off appliances and gadgets that are in stand by state.
  • Set air conditioner’s at a slightly higher temperature in summer and during the winter slightly lower. It will make a difference to your electricity bill
  • Use air conditioner only in the rooms occupied.
  • Use a fan instead of air conditioner, they sometimes give effective cooling for a lower electricity consumption.
  • Avoid opening the fridge door as much as possible
  • Turn off the light when you leave the room.
  • Decrease washing machine water temperature and use a shorter cycle, for most laundry it will still come out clean and fresh
  • Fill the washing machine / dryer / dishwasher before operation. Avoid small loads
  • Use energy saving features in the computer’s operating system control panel.
  • Hang the laundry to dry instead of using the dryer. In most places the laundry will dry quickly.
  • Install solar water heater system.
  • Reduce the water temperature of your geyser

Reduce fuel consumption with these easy tips.

  • When buying another car consider a smaller car with low fuel consumption
  • Avoid high acceleration / deceleration driving.
  • Avoid driving with high motor RPM. Switch gears to a higher one asap.
  • Don’t drive with unnecessary luggage or other items to reduce weight.
  • Close the windows to reduce drag
  • Avoid driving during traffic jams.
  • Avoid unnecessary trips. Rather wal or take public transport.
  • Keep tires with optimal air pressure. This will save energy as well as extending the life of your tires.
  • Keep your car well maintained.
  • Plan your trips so you can minimize the distance or avoid driving through cities with lost of stop starts. Maintaining a steady speed on a highway is normally low on fuel consumption.
  • Don’t be in a rush, a lower speed will make sure you arrive alive, but at a lower fuel consumption. Rather leave earlier.
  • Even if one implements a couple of these you will notice the difference. Just changing your habits can save a lot of money.

Solar Energy or Wind Energy

Solar Energy or Wind Energy which is the best? This really depends on your location. Sometimes solar energy is the best solution and sometimes wind energy is the best solution. At certain locations both will be an excellent solution to your energy and electricity needs.

Solar Energy

The sun which produces solar energy through several means like solar heating, photo voltaic which produces electricity and solar cooking. The sun rays can be used in many ways and are probably one of the most available and reliable sources of solar energy. There is not a single place on earth which would not receive at least some sun (which means solar energy a day). Solar energy can be implemented on a big scale or a small scale. It is easy for households to produce solar energy by installing solar heating or installing solar panels.

Of course in certain places in the world solar energy is more abundant then other places, but this did not stop Germany to become one of the leading countries in solar energy. Germany is not the most favorable country to produce solar energy but they are leading the world. Talk about defying the odds.

Wind Energy

Unless Solar Energy, wind energy is less viable. Wind Energy is mainly available at coastal areas, but it can be available 24 hours a day. Solar energy is not available 24 hours a day. Wind energy is also more difficult to implement on a smaller scale as it will require construction of huge structures. But there are countries which have successfully implemented wind power or wind energy. One of those countries is Denmark Wind Energy vs Solar Energy which even managed to produce more wind energy in one day as what was required.

Conclusion Solar Energy vs Wind Energy

Solar Energy & Wind Energy can both be very viable and can complement each other to power our earth now and in the future

Facts & History of Solar Power

Interested in solar power? How about some facts and history of solar power.

  • Horace Bénédict de Saussure (1740-1799), a Swiss physicist, geologist, and early Alpine explorer was the inventor of the hotbox which later was succesfully used by British astronomer John Herschel to cook food while on expedition in Africa.
  • The well known and respected Albert Einstein received a Nobel Prize in 1921 for his experiments on photo voltaic and solar power.
  • In 1958 Solar power was used to power space exploration equipment such as satellites and space stations. This is probably the first know commercial use of solar energy.
  • In 1981, the first solar powered aircraft was produced by Paul Macready. The aircraft successfully managed to fly from France to England.
  • Germany is major solar power producer despite its less than favorable climate. The energy generated during sunny days is stored in batteries.
  • Energy from the sun travels for approximately 8 minutes to reach Earth.
  • We can produce the same amount of electricity from 1 ton of sand (siliconis used in the production of photo voltaic cells) as burning 500 ton of coal.
  • In 1982, the first large scale power plants was opened in California.

Denmark’s wind farms generated 140% of the country’s electricity needs yesterday

A very windy day broke a record in Denmark on the 9th of July. They produced an astonishingly 40% more power through their wind farms as their daily needs. This feat was accomplished due to an unusually windy day.

Energy not gone to waste.

The extra energy didn’t go to waste. It was exported to Germany, Norway, and Sweden via interconnections between the countries electricity grids.

Denmark is at the forefront of clean and renewable energy and they proven that on the 9th of July 2015.
