Top electric chargers tips and tricks and energy industry technology Texas from Daniel Sumanth: Of course there are three Teslas on the list – it’s the only manufacturer with a range entirely made up of electric models. The Model X is a super-futuristic crossover MPV/SUV with six or seven seats. It’s got that space the old-school way, by being really big – disguising its bulk reasonably effectively with the grille-less design language shared by all Teslas. The panoramic windscreen extends across the roof all the way to the pert sloping tail with concealed spoiler, so it feels amazingly light inside. Ironic, really – it’s as heavy as a Range Rover. The Model X is also devastatingly fast for a car of this size, reaching 62mph in less than five seconds (3.1 seconds for the P100D) and of course, it’s all-wheel drive and has a range similar to many petrol-powered SUVs, around 280 miles between Supercharger stops.

The Model Y is Tesla’s second SUV, and it has been designed to be more manageable and less flashy than the larger Model X. It wouldn’t be unfair to think of the Model Y as a larger version of the Model 3, both cars share similar styling and are even claimed to share 95% of the same technology. This is far from a bad thing. Both the performance and long-range variants of Model Y are four-wheel drive, this means that traction is plentiful, resulting in impressive acceleration 0-60mph times of 4.5 seconds for the Long Range and 3.5 for the Performance. Although these figures are impressive, this small SUV performs well as a family-lugger, too. Space is more than enough for all five passengers, and with 854-litres of luggage space in the back plus 117-litres up front, the weekly shopping trip should be an absolute breeze.
Solar energy systems generally don’t require a lot of maintenance. You only need to keep them relatively clean, so cleaning them a couple of times per year will do the job. If in doubt, you can always rely on specialised cleaning companies, which offer this service from around £25-£35. Most reliable solar panel manufacturers offer 20-25 years warranty. Also, as there are no moving parts, there is no wear and tear. The inverter is usually the only part that needs to changed after 5-10 years because it is continuously working to convert solar energy into electricity (solar PV) and heat (solar thermal). Apart from the inverter, the cables also need maintenance to ensure your solar power system runs at maximum efficiency. So, after covering the initial cost of the solar system, you can expect very little spending on maintenance and repair work.
Starting at just under £37,000, the Ioniq 5 features a superb infotainment system and generous standard kit, while the available space has to be seen to be believed. It’s comfortable, too, so you’ll relish the chance of racking up the miles. We certainly did, which is why we named the Hyundai Ioniq 5 our Car of the Year for 2021. The Kia EV6 is the sister vehicle to the Hyundai Ioniq 5, so it’s a great pick if you love that model’s technology, but aren’t quite as sold on its retro-futuristic looks. The EV6 is arguably the more conventional of the two, and it’s a bit lower and more sporting. This is reflected in its handling, with slightly firmer suspension offering sharper responses. It’s offered in Long Range RWD, Long Range AWD and a high-performance GT version, and the entry-level version is our favourite. It not only offers the best range figure of up to 328 miles from its 77.4kWh battery, but we also found its 7.2-second 0-62mph time to be quick enough.
Since you will be meeting some of your energy needs with the electricity your solar system has generated, your energy bills will drop. How much you save on your bill will be dependent on the size of the solar system and your electricity or heat usage. Moreover, not only will you be saving on the electricity bill, but if you generate more electricity than you use, the surplus will be exported back to the grid and you will receive bonus payments for that amount (considering that your solar panel system is connected to the grid). Savings can further grow if you sell excess electricity at high rates during the day and then buy electricity from the grid during the evening when the rates are lower.
Like size, the weight of the generator depends on the wattage that it can generate. And weight also determines portability. A 2000 watt generator can be carried by one person. Yet a 5000-10,000 watt generator for home use comes with wheels or is stationary in the case of diesel units. Portability is typically not needed for an off-grid household, where a generator can be stationary. However, for trailer use, the smaller portable generators are more convenient. Note: Our household uses two 10 kW Lombardini diesel generators. They’re housed in a generator shed 50 feet from our home. We just alternate between them.
The Audi Q4 e-tron uses the same underpinnings as the Skoda Enyaq iV and the Volkswagen ID.4, so it has an impressive range of up to 316 miles and 125kW rapid-charging. This also means it’s Audi’s most affordable electric car at the moment, and it makes a great family car because it’s spacious inside and comfortable to drive. The Q4 e-tron’s interior is as upmarket as you’d expect from an Audi, and it’s more user-friendly than the ID.4’s cabin as well, without losing out on the amount of technology available. There’s lots of rear leg and headroom, even for adults, and a big boot. The Audi isn’t as good value as the Skoda, but if you want something a bit more upmarket, the Q4 e-tron is a great option.

Are residential solar panels worth it? Estimate residential solar panel cost. Solar panels aren’t cheap: with installation, an average residential 5kW size system runs between $3 and $5 per watt, or $15,000 to $25,000, before tax credits and incentives, according to the Center for Sustainable Energy.
