Solar Panel Installation Tips

Solar Panel Installation Tips

Solar Panels are typically installed on rooftops, building tops, or stand-alone facilities. It is vital to install your solar panel so that it gets the most direct sun exposure - you want to make sure your solar panel is maximally effective year round. To do this, there are several web-based solar resources to help you properly set up and install your solar panels by tracking the position of the sun in the sky over the course of the year.
Position your solar panel in direct sunlight

Solar Panels perform at optimum capacity when placed in direct sunlight. Try to position your photovoltaic array directly under the noontime sun for maximum efficiency from your photovoltaic unit.
Notice obstructions to sunlight

Remove all items unnessary items or trim branches that may be blocking sunlight to your solar unit. Trace the path of the sun in the sky to determine if an object is casting a shadow over your solar photovoltaic panels. If this is the case, then the operating efficiency of your unit will undoubtedly suffer.
Mounting your Solar Panel

Solar Panel Mounts are used to install photovoltaic solar panels. Solar panel mounts come in three main varieties: pole mounts, roof-ground mounts, and flush mounts. Using these mounts, you can install your solar panel onto an RV, on top of or against the side of a pole, on your roof, or even install them as a free-standing unit. You can learn more about installing solar panels using mounts in our mounts section.

Water pumping with solar panels

Water pumping with solar panels

A good way to put solar panels to use is to install a solar-powered water pump for your well. Although windmills have traditionally been used to power such systems, a solar-powered system works just as well, and is equally friendly to the environment.
Your Well Pump

It is important to choose a quality well pump for use with your solar powered well pump system, one that makes the best use of your power and doesn't require an inefficient, wasteful transformer. Your well drilling provider is likely to offer you the industry standard well pump, a 220 volt alternating current model. The problem with such a high-voltage pump system is that the required transformer is extremely wasteful and can be a huge strain on your inverter during startup. This can cause the power to home to dip, and the lights to dim, which can cause a full-out inverter failure unless you have a top-quality inverter. Avoid such a high voltage system if you can, and instead, opt for a 120 volt AC model, which is much more efficient and does not put nearly as much of a burden on your inverter.
The Solar Panel

Your solar panel does not have to have a very high wattage rating in order to run your solar pump, just check with your well-drilling company to determine what wattage rating you need from your solar panel. An important consideration when setting up an outdoor solar panel system for your well pump is to ensure that you purchase a mounting rack that offers plenty of clearance between the ground and your solar panel and keep in it an open area away from trees. You don't want any large pets, floodwater, or falling branches to damage your system.

Solar Panels & Temperature 2

Despite popular belief, the power output of a solar panel decreases with the increase of the panels temperature. The listed power of a solar cell is the power measured under ideal laboratory conditions, which prescribes a temperature of 25 °C. However, on a typical hot summers day, it is not uncommon for a solar cell to reach a temperature of 75 °C. The efficiency of some cheap solar cells can decrease more than 0.5% for every 1 °C above 25 °C. This means that on a hot summers day, the efficiency of a solar cell could drop as much as 25%. It is therefore extremely important to keep your solar panels well ventilated. Make sure the wind is able to cool on all sides, including the underside of the solar panel.

The Temperature Coefficient (Pmax)
The temperature coefficient is a characteristic of solar panels that can differ greatly, especially between cheap panels and quality panels. This characteristic however, should not be overlooked. For example on a hot summers day the temperature of your solar panels may be around 75°C, this will equate to a power loss according to the solar panels temperature coefficient.

With Sanyo Hybrid panels from Gold Coast Solar Power Solutions the temperature coefficient is -0.30% per °C above 25°C. This would equate to a loss of 157W at 75°C just from heat on a 1.05kW solar power system.
However with some cheaper panels offered by other companies the temperature coefficient can be greater than -0.52% per °C above 25°C. This equates to a loss of 273W at 75°C on a 1.05kW solar power system!

So with this cheaper, so called “cost effective” panel this loss alone equates to 116W of a 1.05kW system that you have paid for which is lost compared to the higher quality Sanyo panel on a good summers day! Imagine the extra power loss on a larger system! That is more than a 10% loss in output over a higher quality solar panel, add to that the piece of mind that comes with purchasing from a reputable brand and knowing that they will be around in the years to come to honour their product warranties.. suddenly the quality solar panels look a lot more appealing.

Solar Panel Temperature Efficiency 1

Solar panel temperature is one of the important factors that affects how much electricity your panels will produce. It's ironic – but the more sunshine you get, the hotter the panels get and this in turns counteracts the benefit of the sun.

In some cases the heat factor can reduce your output by 10% to 25% depending on your specific location.

Of course, not all solar panels are affected by heat equally and luckily some do much better at coping with the heat than others. Here's what you need to know.

Temperature Coefficient

If you look at the manufacturer's data sheet you will see a term called "temperature coefficient Pmax". For example the temperature coefficient of a Suntech 190 W (monocrystalline) solar panel is –0.48%. What this means is that for each degree over 25˚C … the maximum power of the panel is reduced by 0.48%.

So on a hot day in the summer – where solar panel temperature on the roof might reach 45˚C or so – the amount of electricity would be 10% lower.

Conversely, on a sunny day in the Spring, fall, or even winter – when temperatures are lower than 25˚C – the amount of electricity produced would actually increase above the maximum rated level.

Therefore, in most northern climates – the days above and below 25˚C would tend to balance each other out. However, in locations closer to the equator the problems of heat loss could become substantial over the full year and warrant looking at alternatives.

Note:For those of you who want to use their solar panels to charge their RV or boat batteries – you'll will need to make sure that the voltage produced by your panel (under high heat scenarios) will be sufficient to recharge your battery – so it's best to order higher voltage solar panels to offset the temperature losses – and also keep the panels clean for maximum output.

Some Solar Cells Respond to Temperature Changes Better than Others

The solar panel temperature affects the maximum power output directly. As solar panel temperature increases, its output current increases exponentially while the voltage output is reduced linearly. Since power is equal to voltage times current this property means that the warmer the solar panel the less power it can produce. The power loss due to temperature is also dependent on the type of solar panel being used.

Typically, solar panels based on monocrystalline and polycrystalline solar cells will have a temperature coefficient in the –0.44% to -.50% range. Sunpower (Monocrystalline) does the best in this regard with a temperature coefficient of –0.38%. It is also the most efficient commercially available solar panel – making it an excellent choice for high temperature areas.

Amporphous Silicon does a bit better. For example, the Sanyo HIT hybrid cells and bifacial cells, which consist of a layer of monocrystalline silicon covered with a thin coating of amorphouse silicon have a lower temperature coefficient of –0.34% - making them another good choice for people looking for high efficiency solar panels in areas closer to the equator.

The best so far in terms of dealing with high temperatures are the Cadmium Telluride solar panels – with a temperature coefficient of –0.25%. However, while they are good with dealing with temperature changes – they are not as efficient at converting sunlight into electricity.

Newer technologies such as CIGS and some of the 4th generation solar cell technologies being developed show show promise of also being less affected by the temperature – but we have to wait until their datasheets are published to know for sure.

Possible Solutions?

Because of the problem of loss of electricity as a result of heat buildup – most installers make sure it is possible for air to flow above and below the solar panels to help keep them cool.

I've recently received plans from a company in India that has developed a mounting rack that cools the panels – and they claim they can boost the output by 30% to 60% in the lab by keeping the panels cooled. Whether they raise the money they are looking for to take their invention to the market remains to be seen – but I suspect such solutions will eventually become available in the not too distant future.

3 main types of solar cells

There are 3 main types of solar cells.

Monocrystalline silicon is the most efficient and produces the smallest solar cells, and therefore the smallest panels. Monocrystalline solar panels are also the most expensive.

Polycrystalline (or multi-crystalline) silicon produces the next most efficient type of solar cell and is the most popular choice as it provides an excellent balance of performance and economy. Recent improvements in polycrystalline panel technology are bringing these modules closer to monocrystalline in size, efficiency and heat tolerance characteristics. The European market has now adopted polycrystalline as the standard.

Amorphous (or thin-film) silicon uses the least amount of silicon and also produces the least efficient solar cells. This means thin film system take up more area than the other two; an important factor to consider in relation to possible future upgrades; i.e. if you'll have enough space left to do so.


In most situations, we recommend the use of quality polycrystalline solar panels for home solar power systems.

How a Maximum Power Point Tracker Works

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.
