Comfort Cooling from the Sun


Solar based cooling solutions by integrating Vapor Absorption Machines with Solar Concentrators. 

The concentrators generate hot water by harnessing solar thermal energy. The hot water is supplied to a Vapor Absorption Machine (VAM). The VAM supplies chilled water which is circulated through cooling coils in the Air Handling Units (AHUs), over which air flows. The air thus cooled can be used for air-conditioning applications through solar cooling system hybridized with conventional cooling system. Balance cooling load, if any, can be met with the conventional cooling system, should solar generated cooling be insufficient. The in-built control logic allows the operation of the conventional cooling system only when there is a shortfall in the solar thermal energy. 

This integrated system offers the advantage of optimizing the use of electricity and maximizing the use of clean, renewable, solar thermal energy, while meeting the cooling load. Solar comfort cooling finds applications in commercial complexes, malls, large offices, hotels and hospitals.

How Japan is helping to solve the water problems of Southeast Asia


Japan has long weathered the storm. Thunderstorms and typhoons throughout the 20th century left Japan’s cities and towns underwater, while urbanisation and industrialisation, especially following WWII, led to water pollution that created a host of sanitation problems.

Thanks to the creation of efficient water management systems and innovative water-saving and wastewater-treatment technologies, Japan’s water quality has undergone remarkable improvements.

Using the technology and know-how accumulated, Japan is now helping to tackle water problems in countries throughout Southeast Asia where water pollution and flooding are threats with massive socioeconomic impact.

Top 6 Things You Didn’t Know About Solar Energy


Installing a concentrating solar power system in Gila Bend, Arizona. The curved mirrors are tilted toward the sun, focusing sunlight on tubes that run the length of the mirrors. The reflected sunlight heats a fluid flowing through the tubes. The hot fluid then is used to boil water in a conventional steam-turbine generator to produce electricity. | Photo by Dennis Schroeder.

Across Africa, the worst food crisis since 1985 looms for 50 million


Flash back story on drought

Harvest should be the time for celebrations, weddings and full bellies in southern Malawi. But Christopher Witimani, Lilian Matafle and their seven children and four grandchildren had nothing to celebrate last week as they picked their meagre maize crop.

Last year’s drought, followed by erratic rains, hit the village of Nkhotakota hard. But this year the rains never came and, for a second year running, the family grain store is empty. If they manage their savings carefully and eat just one small meal a day, they may just have enough food for two more months.

FINAL NOTE. HOW A MAXIMUM POWER POINT TRACKER REALLY WORKS. 4 of 4


Solar Pump. All About Maximum Power Point Tracking (MPPT) Solar Charge Controllers

The Power point tracker is a high frequency DC to DC converter. They take the DC input from the solar panels, change it to high frequency AC, and convert it back down to a different DC voltage and current to exactly match the panels to the batteries. MPPT’s operate at very high audio frequencies, usually in the 20-80 kHz range. The advantage of high frequency circuits is that they can be designed with very high efficiency transformers and small components. The design of high frequency circuits can be very tricky because the problems with portions of the circuit “broadcasting” just like a radio transmitter and causing radio and TV interference. Noise isolation and suppression becomes very important.

There are a few non-digital (that is, linear) MPPT’s charge controls around. These are much easier and cheaper to build and design than the digital ones. They do improve efficiency somewhat, but overall the efficiency can vary a lot – and we have seen a few lose their “tracking point” and actually get worse. That can happen occasionally if a cloud passed over the panel – the linear circuit searches for the next best point, but then gets too far out on the deep end to find it again when the sun comes out. Thankfully, not many of these around any more.

The power point tracker (and all DC to DC converters) operates by taking the DC input current, changing it to AC, running through a transformer (usually a toroid, a doughnut looking transformer), and then rectifying it back to DC, followed by the output regulator. In most DC to DC converters, this is strictly an electronic process – no real smarts are involved except for some regulation of the output voltage. Charge controllers for solar panels need a lot more smarts as light and temperature conditions vary continuously all day long, and battery voltage changes.

Smart power trackers

All recent models of digital MPPT controllers available are microprocessor controlled. They know when to adjust the output that it is being sent to the battery, and they actually shut down for a few microseconds and “look” at the solar panel and battery and make any needed adjustments. Although not really new (the Australian company AERL had some as early as 1985), it has been only recently that electronic microprocessors have become cheap enough to be cost effective in smaller systems (less than 1 KW of panel). MPPT charge controls are now manufactured by several companies.

WHAT IS MAXIMUM POWER POINT TRACKING? 2 of 4


Solar Pump. All About Maximum Power Point Tracking (MPPT) Solar Charge Controllers
There is some confusion about the term “tracking”:

Panel tracking – this is where the panels are on a mount that follows the sun. The most common are the Zomeworks. These optimize output by following the sun across the sky for maximum sunlight. These typically give you about a 15% increase in winter and up to a 35% increase in summer.

This is just the opposite of the seasonal variation for MPPT controllers. Since panel temperatures are much lower in winter, they put out more power. And winter is usually when you need the most power from your solar panels due to shorter days.

Maximum Power Point Tracking is electronic tracking – usually digital. The charge controller looks at the output of the panels, and compares it to the battery voltage. It then figures out what is the best power that the panel can put out to charge the battery. It takes this and converts it to best voltage to get maximum AMPS into the battery. (Remember, it is Amps into the battery that counts). Most modern MPPT’s are around 93-97% efficient in the conversion. You typically get a 20 to 45% power gain in winter and 10-15% in summer. Actual gain can vary widely depending weather, temperature, battery state of charge, and other factors.

Grid tie systems are becoming more popular as the price of solar drops and electric rates go up. There are several brands of grid-tie only (that is, no battery) inverters available. All of these have built in MPPT. Efficiency is around 94% to 97% for the MPPT conversion on those.

WHAT THE HECK IS AN MPPT CHARGE CONTROLLER?  1 of 4


Solar Pump. All About Maximum Power Point Tracking (MPPT) Solar Charge Controllers
This section covers the theory and operation of “Maximum Power Point Tracking” as used in solar electric charge controllers.

A MPPT, or maximum power point tracker is an electronic DC to DC converter that optimizes the match between the solar array (PV panels), and the battery bank or utility grid. To put it simply, they convert a higher voltage DC output from solar panels (and a few wind generators) down to the lower voltage needed to charge batteries.

(These are sometimes called “power point trackers” for short – not to be confused with PANEL trackers, which are a solar panel mount that follows, or tracks, the sun).

SO WHAT DO YOU MEAN BY “OPTIMIZE”?

Solar cells are neat things. Unfortunately, they are not very smart. Neither are batteries – in fact batteries are downright stupid. Most PV panels are built to put out a nominal 12 volts. The catch is “nominal”. In actual fact, almost all “12 volt” solar panels are designed to put out from 16 to 18 volts. The problem is that a nominal 12 volt battery is pretty close to an actual 12 volts – 10.5 to 12.7 volts, depending on state of charge. Under charge, most batteries want from around 13.2 to 14.4 volts to fully charge – quite a bit different than what most panels are designed to put out.

OK, so now we have this neat 130 watt solar panel. Catch #1 is that it is rated at 130 watts at a particular voltage and current. The Kyocera KC-130 is rated at 7.39 amps at 17.6 volts. (7.39 amps times 17.6 volts = 130 watts).

NOW THE CATCH 22

Why 130 Watts does NOT equal 130 watts

Where did my Watts go?

So what happens when you hook up this 130 watt panel to your battery through a regular charge controller?

Unfortunately, what happens is not 130 watts.

Your panel puts out 7.4 amps. Your battery is setting at 12 volts under charge: 7.4 amps times 12 volts = 88.8 watts. You lost over 41 watts – but you paid for 130. That 41 watts is not going anywhere, it just is not being produced because there is a poor match between the panel and the battery. With a very low battery, say 10.5 volts, it’s even worse – you could be losing as much as 35% (11 volts x 7.4 amps = 81.4 watts. You lost about 48 watts.

One solution you might think of – why not just make panels so that they put out 14 volts or so to match the battery?

Catch #22a is that the panel is rated at 130 watts at full sunlight at a particular temperature (STC – or standard test conditions). If temperature of the solar panel is high, you don’t get 17.4 volts. At the temperatures seen in many hot climate areas, you might get under 16 volts. If you started with a 15 volt panel (like some of the so-called “self regulating” panels), you are in trouble, as you won’t have enough voltage to put a charge into the battery. Solar panels have to have enough leeway built in to perform under the worst of conditions. The panel will just sit there looking dumb, and your batteries will get even stupider than usual.

Nobody likes a stupid battery.
