Panasonic launches domestic solar power products

Panasonic is making a big move into the domestic solar panel business.

Next month The Panasonic Group will launch in Japan its HIT(R) 215 Series* household solar power generation systems.

Panasonic will be able to provide overall energy-saving systems for homes that will include rechargeable batteries, heating and air conditioning, security systems and Net-linking gadgets besides solar panels, which will all be hooked up to each other, he said.

Homes will be able to save on utility costs by selling surplus power from solar power generation systems, and using water heaters at night when utility rates are cheaper, he said.

“You will be living with virtually zero carbon-dioxide emissions through creating, saving, storing and managing energy,” Sakamoto said in Tokyo.

It is  the first series of collaborative products to be developed since SANYO became a part of the Group. The launch signifies how the newly extended group has combined its collective strengths for a full-scale entry into the solar cell business.

The new products combine SANYO’s solar power generation modules with Panasonic’s energy management technology, construction materials, and electrical technology, and will be broadly promoted across the companies’ various sales routes, including home appliances, electrical and construction products.

In doing so, the Panasonic Group and aims to establish a position as the top manufacturer in the market with a target share in Japan of at least 35% by 2012.

UK home owners make money from solar panels

UK: From today British home owners can  earn money for the electricity solar PV produces under the feed-in tariff (also known as ‘clean energy cash-back’).

The feed-in tariffs have been a long time coming but they have already increased demand and you can earn up to 8% return on investment.

The tax free, index linked payments work on two levels:

  • Generation tariff – depending on the size of panels, you are paid per kilowatt hour (kWh) of metered energy that panels generate, regardless of whether you use that energy or sell it to the grid. A typical solar system of less than 4 kWp will produce 41.3p per kWh.
  • Export tariff – whatever size panels you have, you can choose to receive either 3p per kWh of electricity or sell it on the open market.

Depending on your energy usage you may need to draw extra electricity from the grid, but the EST say a 2.5 kWp system could produce half a home’s heating needs. Ed Miliband, Energy and Climate Secretary says: “The guarantee of getting an income on top of saving on energy bills will be an incentive to those wanting to make the move to low carbon living. ”

UK homes to benefit from solar panel incentive

UK: Families can earn £900 a year by installing solar panels on their roofs as part of a new Government scheme to pay people to generate their own electricity.

Under the deal, which will start from April this year, households will be paid for electricity fed into the grid from renewable technologies such as solar, wind or energy from waste.

The most attractive rate of return will be on solar panels, which for an average sized three bedroom home could earn households £25,000 over 25 years.

Ed Miliband, the Energy and Climate Change Secretary, expects one in 10 homes will have installed renewable power on their homes in the next decade expects  with the number of homes  with solar panels alone rising from 10,000 today to 700,000 by 2020.

He pointed out that the payments would be tax-free and a return of up to 9 per cent annually was better than any bank could provide.

However campaigners said the scheme, that will add around £11 on the average household bill by 2020 as electricity companies recoup the costs from everyone, is just another “green tax”.

The deal, called feed-in tariffs, will ensure that any households or building that invest in installing renewable electricity, should be paid a good rate of return. People who currently have solar panels must do a deal with their electricity company. The panels cannot provide a home’s entire energy needs as they only work in daylight and the energy they generate cannot be stored. When they are generating electricity, any surplus goes straight into the national grid.

“The guarantee of getting an income on top of saving on energy bills will be an incentive to householders and communities wanting to make the move to low carbon living,” said Miliband.

“The feed-in tariff will change the way householders and communities think about their future energy needs, making the payback for investment far shorter than in the past.

“It will also change the outlook for a range of industries, in particular those in the business of producing and installing small scale low carbon technology.”

Solar panels get the best rate of return under the feed-in tariff, followed by wind turbines and hydroelectric.

Installing solar panels, which cover a space of around 10ft x 10ft on an average sized roof, will cost around £12,500 but this will be paid back in10 years because the households will be paid £900 per annum, plus making £140 savings on the yearly electricity bill.

Mr Miliband also introduced a renewable heat incentive that will pay households for producing their own heat from woodchip boilers or an air source heat pump. A ground source heat pump, that costs more than £1,000 to put in, could be rewarded with £1,000 a year and lead to savings of £200 per year if used instead of oil.

John Sauven, Executive Director of Greenpeace UK, welcomed the scheme but said rates are still too low for communities to invest in expensive long term schemes like hydro electric on rivers or larger turbines.

“For many families, generating their own clean electricity will be an attractive investment,” he said. “However, the level of ambition set by the government’s Feed-in Tariff is still far too low if we are to reach the full potential of small scale renewables.”

Landowners and farmers are angry that the Government has set the rate for energy generated from waste or anaerobic digestion, that could be installed on many farms, so low.
