For renters, solar costs vary depending on whether you use a portable solar setup, join a community solar program or obtain your landlord’s approval for a permanent system. Portable panels and small battery systems can cost from several hundred to several thousand dollars, while a full rooftop installation is usually a larger investment and may require an agreement about ownership and removal. Check your lease and speak with your landlord before making changes to the property. Compare current options through reputable providers, and check energy.gov.au for information about programs that may be available in your state or territory.
