There are many good options now.

Yes, you are right. However, the standard range version stopped supplying in the US because of the tariff change on the Chinese battery supply.

The energy density for LFP is about 110Wh/kg, meanwhile for NMC is around 200Wh/kg. NMC is much bigger. Which means it has smaller packs with the same capacity.

BTW, the NMC has a higher charging and discharging speed. It can reach 5C rate. Which means can charge to full in 12 minutes. Most of the LFP can only do 2C, which means 30 minites to charge from 0 - 100%.

Some places buy all your excess power generation at the same rate or just count by kWh you generated. In this case, it is useful to use net meter, sicne you treat the grid as a giant battery.

@artemisspawnofzeus7732 has the same chemistry but in a different shape.

I agree somehow it is complex. But it may be more stable and could be cheaper if there is some improvement. At the end of the day, people care mostly about cost and stability. I saw many people trying to use electric tilt racks but were eventually chosen to fixed racks. The lifecycle of motors and electronics is a big concern. These solar panels are supposed to be in service for at least 20 years.

DC is not nearly as bad than AC at such voltages.

@@jolting yes you are right. Safety first.

Probably, tracking solar systems has a lot of problems. It is only useful when there is not much space for more solar panels but you need to increase your solar output. Maintenance work for tracking solar systems is very difficult. And the initial cost can be double or even triple compared to the fix tilt racks.

The auto-tracking system looks fancy but is less reliable and expensive. It can create a lot of maintenance problems after installation. Many large solar farms prefer to calculate a fixed tilt that can generate maximum electricity considering the year-round data. In your case probably timer is the most cost-effective solution and it works.

yes, you are right. But without a battery, I am not sure whether the real-time generation can drive the motor, especially in the morning. A 400kW panel in the morning probably can generate 50W real-time power. I guess in most of the cases this type of control system is powered by utility or a centralized supply from a specific group of panels.

@@Renewable_Tek_Bro the good thing is it doesn't have to be fast. you can use a weak motor with a high reduction gearbox.

Good question. Probably, low boiling point fluid can be useful with minimum sunlight radiation.

don't know the project name. It is a project in the Gobi desert in China. Use tracking solar racking system, that is why it is so easy to flip around.

They missed some calculations, they will blame it on covid 😂

@@beregirobert1261 Yes. The product chosen is a tracking solar rack system, which can change the tilt automatically, that is why if the control unit is faulty, the panels can flip around the axis very smoothly. Probably the wind exceeds the highest torque that the tilt control unit can stand for.

can you give more input? Like how big the size of the system you want to know. I can make some new videos related to more examples.

@@Renewable_Tek_Bro At least 1 turbine model in specific terrain. Wind direction make change when you have forest from 1 side. When is better to choose vertical turbine?
