Your EV charger trips overnight. The DNO says the voltage is fine. The charger says otherwise.

So who’s right?

In this video, we dive into one of the biggest challenges facing the modern electrical grid: rising voltages caused by solar PV, battery storage, EV chargers and changing power flows on local networks. We explore ESQCR voltage limits, BS 7671 Regulation 722, open PEN protection, Clause D vs Clause E, EV charger nuisance tripping, voltage rise, solar exports, DNO responsibilities and why some chargers cope better than others.

The Sahara Desert is the largest hot desert on Earth. It gets between 6 and 7 hours of strong, uninterrupted sunlight every day because it is rarely cloudy.

Scientists from organizations like MIT and NASA have calculated that if we covered just 1.2 percent of the desert with solar panels—an area of about 140,000 square kilometers—it would generate twice as much electricity as the entire world uses.

While this sounds like an easy fix for clean energy, building a massive solar farm in the middle of the desert comes with major challenges.

First, transporting that power across continents requires thousands of miles of expensive electrical grids, and storing energy for use at night is still very difficult.

Dust storms would also constantly coat the panels, requiring enormous amounts of water to keep them clean and running efficiently.

Additionally, climate models show that a solar farm of this scale could actually change the local weather.

Solar panels are much darker than desert sand, so they absorb more heat.

If you cover a massive part of the desert in dark panels, it warms the air above them, creating strong updrafts.

This would pull in moisture and cause heavy rain to fall over the Sahara and the neighboring Sahel region, causing plants to grow where it was once dry.

While a green Sahara sounds like a good thing, changing the desert’s climate would alter global wind patterns, which could accidentally cause droughts in places like the Amazon rainforest.

Aurinkovoimaa on rakennettu Suomessa nopeasti. Sitä oli viime vuoden lopulla sitä oli noin 1600 megawattia, joka vastaa Olkiluoto 3:n sähkötehoa. Kasvua tapahtui erityisesti teollisen mittaluokan aurinkosähkökapasiteetissa, mutta valtaosa kokonaiskapasiteetista oli edelleen pientuotantoa. Uusia suuria aurinkosähkökohteista rakennettaan koko ajan,

Suomessakin maanviljelijä voi saada lisää taloudellista hyötyä sijoittamalla pelloilleen pystyyn asennettavia, kaksipuoleisia aurinkopaneeleita. Turun yliopiston tutkijoiden mukaan aurinkosähkön tuotanto ja perinteinen maanviljely voidaan yhdistää tehokkaasti.
