Overall, democratization of utility and finance is great, but this article is so inconsistent with the pricing and statements it really reads like a sycophantic llm wrote the entire thing.
Here is the actual numbers from Sun King on their entry level system (Home Plus):
Basic (dc-only) panel for lighting and cellular/usb use:
Lighting: 1 x 240-lumen LED tube light, 2 x 120-lumen LED hanging lights. Up to 43 hours of light on a single charge on low-power mode
Battery: 3.2 V, 19.2 Wh lithium ferro-phosphate (LFP) battery. 10-year battery lifespan with typical daily use (over 2,500 cycles)
Solar: 7 Wp, 9 V solar panel with 8-metre rodent-resistant cable
Output ports: 2 x 12 V DC output ports for lighting (550 mA max. total), 1 x USB-A phone charging port (5 V, 1 A)
>₦2,000 per week ($1.39 USD/week) x 60 weekly payments, ₦3,500 down payment ($2.43 USD)
= $85.83
=~ 20kWh over that 60 week period (Just over 1 year), over 10 years = ~200 kWh... ~$0.429/kWh (reasonable given the lighting hardware is included, and the only thing that should need changing during that time is the lfp battery which the price is dropping very quickly on).
Larger dc system:
Home 500X + Pedestal Fan
Lighting: 4 x LED tube lights with individual wall switches, 200 lumen per tube light on max setting, 20 times brighter than a kerosene lamp, One motion-sensing 100 lumen security lamp
Battery: 141 Wh lithium-ion NMC battery, Up to 19 hours of runtime on low power mode. 5-year battery lifespan with typical daily use
Solar: 50 W, polycrystalline solar panel with aluminium frame and a 6 m cable
Charging Ports: 2 x 5 V/1.8 A USB ports for charging mobile devices, 4 x 12 V(+/-3 V) ports. One port is specially designed to power Sun King DC appliances
>₦5,600 per week ($3.82 USD/week) x 60 weekly payments, ₦15,500 down payment ($10.78 USD)
= $239.98
=~ 147kWh over that 60 week period (Just over 1 year), over 10 years = ~1300 kWh... ~$0.184/kWh (again very reasonable given the lighting hardware is included, and again the nmc battery at 5 years which the price and quality of is improving very quickly on).
So yes, this does seem pretty viable in terms of Upfront, TCO and payment options.
- tgtweak 11mo agoThe larger systems (solar + AC Inverter + home-scale battery): PowerHub Core (2 kW AC inverter 230VAC, 2.5kWh lfp battery storage, 1800-2700W solar panels - ₦48,000 per week, 80 weekly payments, ₦240,000 down payment ₦4,080,000 ($2,836.94 USD) financed or ₦2,400,000 ($1668.79 USD) buy outright PowerHub Plus (3.3kW AC inverter 230VAC, 5.0 kWh lfp battery storage, 1800-3600W solar panels - ₦64,000 per week, 80 weekly payments, ₦320,000 down payment ₦5,440,000 ($3782.58 USD) financed or ₦3,200,000 ($2225.05 USD) buy outright = yields ~47,600kWh over 10 years, =$0.0350-0.0795/kWh (2.5kWh/1800W system bought outright vs 5kWh/1800W system on finance), very competitive, with storage included. These are the "starting from" costs - so likely the with 1800w of panels on both systems. Pretty crazy cost of financing, but still pretty reasonably priced for an installed, warrantied system. For reference, that's cheaper than most of these ecoflow-style "solar generators" with ~3.3kWh batteries, 3000W output and 4x400W solar panels cost here (typically $4500-5000 USD).
