The ability to be 100% energy independent seemed a lofty dream just a few years ago. Now, thanks to the latest developments in solar technology, that dream could become reality a lot sooner than expected. Reaching a state of energy independence is important for two main reasons:\u00a0<\/span><\/p>\n Imagine living a life where you didn\u2019t need to rely on a utility provider for electricity. It sounds too good to be true, but let\u2019s take a closer look at some of the current and emerging technologies that help make this possible.\u00a0<\/span><\/p>\n One of the reasons an energy-independent future seemed so far away was due to the poor efficiency of solar panels. The technology started out as a clever way of generating electricity from solar energy, but with one significant drawback: they were under 20% efficient.\u00a0<\/span><\/p>\n As such, experts spent the last few years developing better solar panel technology to increase the efficiency to heights we\u2019ve never seen before. Most solar panels now sit above 20%, with the majority falling between 21 and 23% efficiency. Furthermore, developers like <\/span>Oxford PV<\/span> have managed to go beyond this, topping out at an industry-leading 25% efficiency.\u00a0<\/span><\/p>\n The growth in solar panel efficiency means they\u2019re better at their job, which allows for more solar energy to be converted into electricity. In turn, houses and commercial buildings can harness more renewable energy from the sun \u2013 to the point where it\u2019s possible for some properties to rely on just solar energy throughout the day.\u00a0<\/span><\/p>\n The simple presence of solar batteries adds more weight to the idea of being energy independent. Introduced as a new addition to a solar system, batteries help you store energy for later use. They\u2019re now provided by any <\/span>commercial and residential solar installer<\/span>, unlocking a whole new way to use solar energy.\u00a0<\/span><\/p>\n Batteries themselves are good enough to assist with energy independence because they let you use solar energy during sub-optimal conditions. For example, the battery stores solar power during the day and lets you use it at night. Even though there\u2019s no sun for the solar panels to absorb, your property manages to operate using solar energy.\u00a0<\/span><\/p>\n It was already a big step, but new developments make these batteries even better.\u00a0<\/span><\/p>\n Companies are slowly realising that traditional lithium-ion batteries aren\u2019t optimal for this type of technology. While these batteries work for other uses, the nature of solar batteries means they need to survive many cycles and be suitable for charging and discharging frequently. According to <\/span>Kings Research<\/span>, the following solar battery technologies are creeping into the market:\u00a0<\/span> This particular vein of technology keeps improving, and this is great news for energy independency. The end goal is a battery that can store enough solar energy to power an entire home or building for at least a day or more. Furthermore, there\u2019s the idea of making batteries smaller yet still highly effective, allowing for multiple battery storage options on-site. It could allow homeowners or commercial properties to store electricity for days via solar power, reducing their need to dip into the national grid.\u00a0<\/span><\/p>\n While inefficiencies held solar panels back for years, another issue coincides with this: their general structure. Try as you might, it\u2019s not possible to install <\/span>solar panels<\/span> that cover an entire roof. There will always be slight gaps here and there \u2013 and sometimes a significant portion of the roof is uncovered due to the size and shape of the panels.\u00a0<\/span><\/p>\n To provide some context behind this, solar panels normally take up just 40-80% of usable roof space. In terms of the total roof area, they\u2019re only covering a maximum of 60%. That wastes a lot of real estate, but that\u2019s where integrated solar technology makes significant strides.\u00a0<\/span><\/p>\n The most well-known example of this is the <\/span>Tesla solar roof<\/span>, which gets rid of solar panels in favor of a built-in solar system. Effectively, your entire roof is one big network of solar roof tiles \u2013 which means it usually offers this level of coverage:\u00a0<\/span><\/p>\n Integrating solar technology like this means you maximize solar production and can therefore use and store more solar energy. When combined with an efficient battery, it brings households way closer to a sense of energy independence. Moreover, while solar roof tiles aren\u2019t as efficient as panels right now, it\u2019s still a relatively new technology. We\u2019ve already seen how solar panels have managed to increase their efficiency, so expect integrated solar solutions to follow.\u00a0<\/span><\/p>\n The best thing about this technology is that it can be implemented across new-build homes with ease, meaning homeowners can move into properties that are more energy independent than ever before.\u00a0<\/span><\/p>\n There\u2019s not much research or discussion on this yet, but experts believe that EVs hold the key to better energy independence. It\u2019s due to their batteries being large and efficient enough to power a home for numerous days. The fascinating idea here is that a solar system diverts energy to the car, powering the battery, and then the car sends energy back to the home in the evening if required.\u00a0<\/span><\/p>\n When used correctly, it can create a situation where EVs become backup power generators that receive full charges from solar energy. There\u2019s so much potential here, but more research must be done to see if it\u2019s truly as feasible as it seems.\u00a0<\/span><\/p>\n It\u2019s critical to note that many of these technologies are either theoretical or just starting to emerge into the public space. Energy independence is likely impossible for many households or businesses right now, but it won\u2019t be long before we see increased numbers of properties running on pure solar energy.\u00a0<\/span><\/p>\n \u00a0<\/p>\n<\/p><\/div>\n\n
