TLDR: With the increased power costs and increased expected heat this coming year, I've been contemplating the idea of installing a 10kwh solar system on my house here in Brisbane for $5000 in hope to create a zero monthly electricity bill, and I'd greatly appreciate your thoughts and advice on this matter.
Here's my situation in full:
Solar System Offer:
-Keeping in mind that installation prices have dropped but aware of making sure the installion is done well and that even thoigh I hear that 1 kwh = 4kwh/day, im unsure if this is based more on a 4.5 hour day
-Also keeping in mind the rule of thimb that what ever they say you'll produce, you're more likely to only get 85% of this anount in kwh production. [kwh=amount/(0.1*0.85)
- Found an offer for a 10 kWh solar system at $5,000, including installation.
-Payback model is interest free $110/fornight
- Expected solar production: 250-300 kWh per week, considering current weather conditions.
- Brisbane receives an average of 6-6.3 hours year round of sunlight daily, which is quite good.
[b]Current Electricity Usage:[/b]
- In July (coldest month): We use around 10 kWh/day.
- In February-March (hottest months): Our usage spikes to about 14.5 kWh/day.
- Maximum daily export capacity to the grid is 10 kWh, with a reimbursement rate of $0.08 per kWh.
- We buy electricity from the grid at a rate of $0.25 per kWh.
My Questions:
1. Do you think a 10 kWh solar system is sufficient to reduce our annual electricity bills to zero, considering the variation in solar production and our usage patterns throughout the year?
2. With our surplus electricity being reimbursed at $0.08 per kWh and a purchase cost of $0.25 per kWh, does it make financial sense to go solar atm¿
I'm eager to hear your experiences and insights, especially if you've dealt with a similar situation. Any advice on sizing the system correctly and optimizing savings would be invaluable.
Thank you in advance for your help?
