This article will focus on solar thermal vs. Solar energy is one of the fastest-growing sources of clean energy. Therefore, there is rampant use of solar panels, which involves the absorption of sunlight and converting it into usable energy. However, these people must decide the technology they want to use between solar photovoltaic and solar thermal. A majority of them barely know the difference between the two types of solar technologies. In some instances, some households end up installing both models in their home. Well, this is a combination that can work well when one wants to make the most of the efficiency of the solar thermal for their hot water needs and solar photovoltaic for other uses as well as the ability to sell excess electricity back to the grid.

Actually, with the new hybrid panels, people will be able to use both solar PV and solar thermal within the same unit. That will increase the use of hybrid systems in households. In this piece, we will give an ultimate overview of solar thermal vs. In this technology, the panels on rooftops act as the collectors for sunlight and they heat the liquid in the tubes which later goes into a cylinder ready for use.

The fluid that is usually heated by the concentrated sunlight can either be in the form of a liquid or a gas. For example, it can either be water, oil, helium, salts, or air, among others. The solar thermal system differs from solar photovoltaic in that the solar thermal power generation works through the concentration of sunlight to produce heat. The heat, in turn, drives a heat engine which turns a generator to make electrical energy. The energy is suitable for use in industries, commercial and residential sectors. Solar thermal is mainly ideal for water heating purposes. There are two types of hot water tanks.

The first one heats the drinking water and usually consists of a steel tank which is filled with a heat exchanger and the drinking water. The second one is a combination tank that supplies both hot water and freshwater to the heater. The tank that integrates the duel system has two smaller tanks that are inside that help keep the water for the different tasks separate. The underlying principle of solar thermal heating is harnessing the sunlight and converting it into heat, which is then transmitted into your business or home heating system in the form of space heating or hot water. Heat is generated through solar panels mounted on the rooftop which are used in conjunction with a collector, a boiler, or an immersion heater.

The solar collector uses the rays of the sun to heat a transfer fluid, which is usually a mixture of glycol antifreeze and water, which prevents the water from freezing. The water that has been heated from the collector is then pumped into a heat exchanger which is located inside the water tank. The heat from the exchanger will heat the water that is inside the tank.

The water will then flow back to the collectors for reheating after the liquid releases its heat. The controller helps ensure that the fluid circulates to the collector when there is enough heat available. In the past, solar thermal systems were cheaper than solar PV panels. Today, the two technologies are relatively costly, and therefore, that is not a significant determinant.

Thus, one of the main reasons to select solar thermal is to save on space. While the solar PV system can take up to 10m2 of roof space, the solar thermal can only occupy 3mm2. However, solar panel technology is making improvements to see this number consistently increase. The technology in solar thermal is not as complex as the one in the solar PV panels. Solar thermal comes in handy when you want hot water as it is an ideal solution for water heating and space. Heat storage is an efficient and more convenient method which makes the solar thermal panels more attractive for large-scale production use. That is because it can store heat within the day and convert it into electricity later at night. The storage capacity of solar thermal helps boost both economics as well as the dispatch-ability of solar power.

Life expectancy ranges between manufacturers, but many panels produced today carry a year warranty - with a life expectancy of up to 40 years. Oil, coal, and gas used to produce conventional electricity is often transported cross-country or internationally. This transportation has a myriad of additional costs, including monetary costs, pollution costs of transport, and roading wear and tear costs, all of which is avoided with solar.

On grid means a house remains connected to the state electricity grid. Off grid has no connection to the electricity grid, so the house, business or whatever being powered is relying solely on solar or solar-hybrid. The ability to produce electricity off the grid is a major advantage of solar energy for people who live in isolated and rural areas. Power prices and the cost of installing power lines are often exorbitantly high in these places and many have frequent power-cuts.

Many city-dwellers are also choosing to go off the grid with their alternate energy as part of a self-reliant lifestyle. A particularly relevant and advantageous feature of solar energy production is that it creates jobs. Solar jobs come in many forms, from manufacturing, installing, monitoring and maintaining solar panels, to research and design, development, cultural integration, and policy jobs. The book Natural Capitalism offers a good perspective on the employment potential of green design and a prudent approach to using resources.

The book proposes that while green technology and associated employment can be expensive, much greater money can be saved when combined with proven "whole-system" efficiency strategies e. One of the biggest advantages of solar energy is the ability to avoid the politics and price volatility that is increasingly characterizing fossil fuel markets. The sun is an unlimited commodity that can be sourced from many locations, meaning solar is less vulnerable to the price manipulations and politics that have more than doubled the price of many fossil fuels in the past decade. While the price of fossil fuels have increased, the per watt price of solar energy production has more than halved in the past decade — and is set to become even cheaper in the near future as better technology and economies of scale take effect.

Of course, a new form of politics has emerged with regard to government incentives and the adoption of solar, however these politics are arguably minor compared to the fossil fuel status quo. Destruction can come in many forms, from destruction through accepted extraction methods, to more irresponsible practices in vulnerable areas, to accidents. The Niger Delta is an example where excessive and irresponsible oil extraction practices have poisoned fishing deltas previously used by villagers as the main source of food and employment, creating extremely desperate poverty and essentially decimating villages [2]. A more widely known, but arguably lower human-cost incident is the BP oil spill in the Gulf of Mexico.

It killed 11 people and spilled thousand cubic meters of crude oil into the sea. Solar technology is currently improving in leaps and bounds. Across the world, and particularly in Europe, savvy clean technology researchers are making enormous developments in solar technology. What was expensive, bulky, and inefficient yesterday, is becoming cheaper, more accessible, and vastly more efficient each week.

The biggest disadvantage of solar energy is that it's not constant. To produce solar electricity there must be sunlight. So energy must be stored or sourced elsewhere at night. Beyond daily fluctuations, solar production decreases over winter months when there are less sunlight hours and sun radiation is less intense. This means that a fairly vast amount of surface area is required to produce adequate electricity.

However, efficiency has developed dramatically over the last five years, and solar panel efficiency should continue to rise steadily over the next five years. Solar inefficiency is an interesting argument, as efficiency is relative. While there are many solar drip feed batteries available, these are currently costly and bulky, and more appropriate to small scale home solar panels than large solar farms.

Solar panels are bulky. This is particularly true of the traditional silicon crystalline wafer solar modules. These are the large solar panels that are covered in glass. The downfall is that thin-film is currently less efficient than crystalline wafer solar. One feature of solar energy is that it spurs discussion and re-assessment of the importance and interaction between economics, environment, and investment.

While not everybody is in favor of solar, the fact that there is discussion about the validity of the status quo is a fascinating development. The monopolistic nature of many industries, the pitfalls of solely focusing on economics, and environmental disregard, are increasingly central topics. At a practical level, many governments and state authorities are encouraging solar use through incentives such as subsidies, rebates and tariffs. California is an interesting example of such measures in action. Your email address will not be published.
